Abstract, futuristic image generated by AI

While the cloud is often safer than on-premises computing, it’s still vulnerable to a wide range of security threats. In 2023, 39% of businesses were reported to have experienced a breach in their cloud environment last year, up from 35% the year before.

The challenge for cloud security teams is to embrace the benefits of cloud computing while safeguarding their companies’ digital assets. 

As such, understanding and adapting to the latest cloud security trends is critical. Equally vital is the need for cloud security teams to continually uplevel individual technical skills to keep up with the latest security threats. 

Read on to learn more about the current trends shaping cloud security and explore how these trends will impact the technical skills needed to keep your organization and its data secure. 

What Is Cloud Security?

 A surprising number of organizations that use the cloud haven’t taken the necessary precautions to protect their sensitive data. While 75% of organizations report that 40% or more of their data in the cloud is sensitive, less than half of this data is encrypted. Given that the number of global cyberattacks can increase by 38% in a single year, protecting this data is vital.

Cloud security is the discipline charged with protecting the data, applications, and infrastructure hosted in these cloud environments from potential threats and vulnerabilities. Cloud security is a critical aspect of cloud computing, as organizations increasingly rely on cloud services to store and process sensitive information. The primary goal of cloud security is to ensure the confidentiality, integrity, and availability of data and resources in the cloud.

Top Cloud Security Trends

As cybersecurity threats evolve, organizations and industry professionals also need to look at security measures and adapt their skills to keep up. The best way to do so is by proactively responding to the many emerging trends taking shape across the industry.

#1. Zero-Trust Architecture

The traditional network security perimeter is becoming obsolete. In the past, organizations relied heavily on a well-defined perimeter to safeguard their digital assets. However, the rise of sophisticated cyber attacks, insider threats, and the increasing prevalence of remote work have collectively rendered the traditional perimeter defenses inadequate.

Zero trust architecture challenges the assumption that entities within the network, once verified, can inherently be trusted. Instead, it operates on the principle of “never trust, always verify.” Whether it be the threat of bad actors, or simply the existence of human error, every user, device, or application is treated as potentially untrusted. This trend requires a shift in mindset, with a focus on continuous verification of identity and strict access controls.

#2. Multi-Cloud Security

The adoption of multi-cloud environments represents a strategic response to the diverse needs and requirements of modern organizations. As businesses increasingly rely on cloud services for various aspects of their operations, the utilization of multiple cloud providers becomes a pragmatic approach. The rationale behind multi-cloud adoption is often rooted in the desire to avoid vendor lock-in, optimize costs, and capitalize on the unique strengths of different cloud providers. 

With organizations leveraging multiple cloud providers, ensuring consistent security across these environments is crucial. Professionals need expertise in managing security protocols and solutions that transcend the boundaries of individual cloud platforms.

#3. AI and Machine Learning in Security

The integration of AI and machine learning (ML) into the realm of cybersecurity marks a paradigm shift in the way organizations defend against increasingly sophisticated cyber threats. These tools empower security systems to evolve from rule-based, reactive measures to proactive, adaptive defense mechanisms. The ability of these systems to analyze vast amounts of data, recognize patterns, and discern anomalies in real time significantly enhances the detection and mitigation of cyber threats. 

In the context of cloud security, where the scale and diversity of data are intense, harnessing the power of AI and ML for threat detection and analysis becomes paramount. Managing AI-driven security solutions requires a holistic understanding of the organization’s infrastructure, data flows, and application landscape. Professionals must be adept at configuring, monitoring, and fine-tuning AI algorithms, as well as skilled in interpreting the insights generated by these models, in order to translate them into actionable intelligence for a timely and effective response.

#4. DevSecOps Integration

The integration of security into the DevOps pipeline, known as DevSecOps, is a transformative approach that places security at the core of the DevOps lifecycle. This shift represents a departure from the traditional paradigm where security was often treated as an afterthought, relegated to the final stages of the development process, which often led to vulnerabilities persisting through multiple development cycles. 

Instead, the integration of security into DevOps involves automating security processes, incorporating security testing into the continuous integration/continuous deployment (CI/CD) pipeline, and fostering a culture where security is everyone’s responsibility. This requires proficiency in tools and technologies that facilitate automated testing, vulnerability scanning, and code analysis. Additionally, professionals operating in the DevSecOps space must collaborate with development and operations teams, breaking down silos that traditionally separated these functions – ensuring that security is not just a checkbox, but a shared responsibility throughout the development lifecycle.

#5. Cloud-Native Security

The surge in popularity of cloud-native architectures signifies a transformative shift in how applications are designed, built, and deployed. They are designed to take full advantage of cloud-computing environments, thus providing security beyond traditional architectures. In this landscape, understanding the intricacies of securing cloud-native components such as microservices, containers, and serverless computing is not just a best practice; it’s a non-negotiable for organizations embracing the agility and scalability offered by cloud environments.

Cloud-native security requires a holistic understanding of the entire application landscape. Professionals must collaborate closely with development and operations teams, ensuring that security considerations are an integral part of the design and implementation. The ability to navigate the complexities of this environment and its components is not only a skill set, but a strategic advantage for organizations seeking to harness the full potential of cloud-native technologies securely. 

#6. IoT Security

The proliferation of Internet of Things (IoT) devices represents a technological revolution, connecting everyday objects to the internet and transforming them into intelligent, data-generating entities. However, this interconnected ecosystem also introduces unprecedented security challenges. As IoT devices become ubiquitous, organizations must recognize and address the new entry points for potential security breaches that arise from the sheer scale and diversity of these interconnected devices. 

Professionals in cloud security play a critical role in mitigating the risks associated with IoT deployments. Unlike traditional computing environments, IoT ecosystems encompass a vast array of devices with varying levels of computing power, communication protocols, and security postures. Cloud-security experts need to be adept at implementing robust and adaptive security measures that account for IoT devices.

#7. End-to-End Encryption

With an increasing emphasis on data privacy, the trend toward end-to-end encryption (E2EE) is picking up speed, marking a fundamental shift in how organizations safeguard their sensitive information. This encryption paradigm, where data is securely encrypted throughout its entire journey, is gaining momentum as a proactive measure to counteract the ever-present threats of unauthorized access and data breaches.

End-to-end encryption extends beyond the traditional focus on securing data in transit. While protecting information as it moves between devices or across networks remains crucial, the trend recognizes the need for a more comprehensive approach. Cloud-security professionals are now tasked with implementing encryption measures that span the entire data lifecycle – encompassing data at rest, in transit, and within applications and databases.

#8. Evolution of Identity and Access Management

As the traditional network perimeter becomes porous and digital ecosystems grow in complexity, identity and access management (IAM) emerges as a linchpin in safeguarding sensitive data, applications, and resources from potential threats. IAM’s evolution is driven by the critical need to go beyond conventional username-password authentication methods. Instead it serves as a strategic response to the sophisticated tactics employed by bad actors, recognizing that static credentials alone are often insufficient to protect against increasingly sophisticated attacks. 

Cloud-security professionals are witnessing a shift towards more advanced IAM solutions that incorporate cutting edge technologies – think biometrics, adaptive authentication, and continuous monitoring – to enhance the granularity and resilience of access controls. To stay ahead of these IAM advancements, it’s critical to remain proactive and stay well-informed about emerging technologies, industry best practices, and evolving threats. 

#9. Serverless Security Challenges

Serverless computing is gaining popularity. While lauded for its scalability, cost-effectiveness, and streamlined development, it also introduces a distinctive set of emerging security challenges that demand the attention of cloud-security professionals.

Unlike traditional monolithic applications, serverless functions operate independently and are often executed in ephemeral containers. This requires cloud-security experts to focus on implementing robust authentication and authorization mechanisms, ensuring only authorized entities can invoke and interact with these functions. 

Monitoring for potential vulnerabilities in a serverless environment presents a unique challenge. Traditional security tools may not seamlessly integrate with the event-driven nature of serverless architectures. Cloud-security experts need to deploy specialized monitoring solutions capable of providing real-time insights into the execution and performance of serverless functions. By leveraging these serverless-specific security tools, professionals can detect anomalies, unauthorized access attempts, and potential security breaches, allowing for swift responses to emerging threats.

#10. Regulatory Compliance in the Cloud

Regulations for data protection have had a centralizing impact on cloud security. Organizations now have to navigate a complex web of global regulations to ensure the secure and compliant handling of sensitive information. As data breaches and privacy concerns escalate, compliance with regulations like GDPR, HIPAA, and others has become paramount, turning regulatory adherence into a critical facet of cloud-security strategy.

The migration of data and applications to the cloud introduces complexities in ensuring compliance with these regulations. Failure to do so can result in legal, financial, and reputational repercussions. Cloud service providers play a role in managing the security of the underlying infrastructure, but organizations bear the responsibility for securing their applications and data within the cloud environment. Cloud-security professionals are at the forefront of addressing this challenge, wielding technical skills to implement and maintain robust compliance measures tailored to the specific requirements of each regulation.

Google Cloud Platform, or GCP. While it may have been a latecomer to the cloud party compared to AWS and Azure, don’t let that fool you. GCP has managed to carve a unique identity, packed with a wide range of features and an open-source spirit that aligns closely with modern development cultures. More than just another cloud provider, it’s a comprehensive suite of solutions that cater to varied business needs, from startups grappling with scale to Fortune 500 companies managing vast, complex architectures.

In this post, we’ll unpack what GCP is, delve into its key features, discuss the skill set needed to master it, and shed some light on the hiring outlook for those armed with GCP expertise. 

What is Google Cloud Platform?

When most people hear “Google,” they think of the search engine that’s virtually synonymous with the internet itself, or perhaps Android, the popular mobile operating system. But Google’s reach goes far beyond that, extending into the realm of cloud computing with Google Cloud Platform, or GCP for short. Launched in 2011, GCP might have been late to the cloud party compared to Amazon’s AWS (which emerged in 2006), but it came in strong, leveraging years of experience running high-traffic, high-availability services like Google Search, YouTube, and Gmail.

So what exactly is GCP? At its most basic, Google Cloud Platform is a collection of cloud computing services. It allows users to do everything from hosting websites and applications to crunching big data to building and implementing machine learning models. But saying that GCP is a collection of cloud services is a bit like saying a Swiss army knife is a cutting tool — it’s accurate but fails to capture the versatility and depth of what’s on offer.

GCP provides a range of services under different computing models — Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and even serverless computing. It offers these services on a global network — the very same network that handles the billions of Google search queries and YouTube videos that people consume every day. This ensures both rapid and reliable service execution and delivery.

But what really sets GCP apart is its core features, which boil down to three main points:

Open Cloud: GCP is deeply committed to open-source technologies. This is evident in its robust support for Kubernetes, the open-source container orchestration platform that Google originally designed. This focus on openness allows for smoother transitions and interoperability between different cloud providers and on-premises solutions.

Data at the Core: Google’s heritage is all about handling data, whether it’s sorting it, analyzing it, or making it useful. This data-centric ethos is woven into every fiber of GCP, especially in its array of database solutions, data analytics tools, and machine learning services.

Security First: Given its history of managing massive amounts of sensitive consumer data, Google naturally places a high premium on security. This is manifested in GCP’s stringent identity management protocols and extensive network security features.

By now, you should have a sense that GCP isn’t merely playing catch-up; it’s a serious contender with its own unique strengths and offerings. As it continues to grow in market share, so does the range of career opportunities for professionals skilled in navigating this expansive platform.

But it’s not all technical! Given that Azure is often pivotal in business solutions, you might also be tested on your ability to align Azure’s capabilities with business goals, cost management, or even disaster recovery strategies.

1. Deploy a Web App Using Azure CLI

The Azure command-line interface (CLI) is an essential tool for developers and administrators to manage Azure resources. This question tests a candidate’s proficiency with Azure CLI commands, specifically focusing on deploying web applications to Azure.

Task: Write an Azure CLI script to deploy a simple web app using Azure App Service. The script should create the necessary resources, deploy a sample HTML file, and return the public URL of the web app.

Input Format: The script should accept the following parameters:

  • Resource group name
  • Location (e.g., “East U.S.”)
  • App service plan name
  • Web app name

Constraints:

  • The web app should be hosted on a free tier App Service plan.
  • The HTML file to be deployed should simply display “Hello Azure!”

Output Format: The script should print the public URL of the deployed web app.

Sample Code:

#!/bin/bash

# Parameters

resourceGroupName=$1

location=$2

appServicePlanName=$3

webAppName=$4

# Create a resource group

az group create --name $resourceGroupName --location $location

# Create an App Service plan on Free tier

az appservice plan create --name $appServicePlanName --resource-group $resourceGroupName --sku F1 --is-linux

# Create a web app

az webapp create --name $webAppName --resource-group $resourceGroupName --plan $appServicePlanName --runtime "NODE|14-lts"

# Deploy sample HTML file

echo "<html><body><h1>Hello Azure!</h1></body></html>" > index.html

az webapp up --resource-group $resourceGroupName --name $webAppName --html

# Print the public URL

echo "Web app deployed at: https://$webAppName.azurewebsites.net"

Explanation:

The script begins by creating a resource group using the provided name and location. It then creates an App Service plan on the free tier. Subsequently, a web app is created using Node.js as its runtime (although we’re deploying an HTML file, the runtime is still needed). A sample HTML file is then generated on the fly with the content “Hello Azure!” and deployed to the web app using `az webapp up`. Finally, the public URL of the deployed app is printed.

2. Configure Azure Blob Storage and Upload a File

Azure Blob Storage is a vital service in the Azure ecosystem, allowing users to store vast amounts of unstructured data. This question examines a developer’s understanding of Blob Storage and their proficiency in interacting with it programmatically.

Task: Write a Python script using Azure SDK to create a container in Azure Blob Storage, and then upload a file to this container.

Input Format: The script should accept the following parameters:

  • Connection string
  • Container name
  • File path (of the file to be uploaded)

Constraints:

  • Ensure the container’s access level is set to “Blob” (meaning the blobs/files can be accessed, but not the container’s metadata or file listing).
  • Handle potential exceptions gracefully, like invalid connection strings or file paths.

Output Format: The script should print the URL of the uploaded blob.

Sample Code:

from azure.storage.blob import BlobServiceClient, BlobClient, ContainerClient

def upload_to_blob(connection_string, container_name, file_path):

    try:
        # Create the BlobServiceClient

        blob_service_client = BlobServiceClient.from_connection_string(connection_string)

        # Create or get container

        container_client = blob_service_client.get_container_client(container_name)

        if not container_client.exists():

            blob_service_client.create_container(container_name, public_access='blob')

        # Upload file to blob

        blob_client = blob_service_client.get_blob_client(container=container_name, blob=file_path.split('/')[-1])

        with open(file_path, "rb") as data:

            blob_client.upload_blob(data)

        print(f"File uploaded to: {blob_client.url}")     

    except Exception as e:

        print(f"An error occurred: {e}")
# Sample Usage

# upload_to_blob('<Your Connection String>', 'sample-container', 'path/to/file.txt')

Explanation:

The script uses the Azure SDK for Python. After establishing a connection with the Blob service using the provided connection string, it checks if the specified container exists. If not, it creates one with the access level set to “Blob.” The file specified in the `file_path` is then read as binary data and uploaded to the blob storage. Once the upload is successful, the URL of the blob is printed. Any exceptions encountered during these operations are caught and printed to inform the user of potential issues.

using System.Linq;

public static class GetDocumentFunction

{

    [FunctionName("RetrieveDocument")]

    public static IActionResult Run(

        [HttpTrigger(AuthorizationLevel.Function, "get", Route = null)] HttpRequest req,

        [CosmosDB(

            databaseName: "MyDatabase",

            collectionName: "MyContainer",

            ConnectionStringSetting = "AzureWebJobsCosmosDBConnectionString",

            Id = "{Query.docId}")] dynamic document,

        ILogger log)

    {

        log.LogInformation("C# HTTP trigger function processed a request.");

        if (document == null)

        {

            return new NotFoundObjectResult("Document not found.");

        }

        return new OkObjectResult(document);
    }
}

Explanation:

This Azure Function uses the Azure Functions 3.x runtime and is written in C#. It’s triggered by an HTTP GET request. The function leverages the CosmosDB binding to fetch a document from Cosmos DB using the provided `docId` query parameter. If the document exists, it’s returned as a JSON response. Otherwise, a 404 Not Found response is returned with an appropriate error message.

Note: This code assumes the Cosmos DB connection string is stored in an application setting named “AzureWebJobsCosmosDBConnectionString.”

  • Ensure the VM is of size `Standard_DS1_v2`.
  • Set up the VM to use SSH key authentication.
  • Assume the SSH public key is located at `~/.ssh/id_rsa.pub`.
  • Handle exceptions gracefully.

Output Format: The script should print the public IP address of the created VM.

Sample Code:

from azure.identity import ClientSecretCredential

from azure.mgmt.compute import ComputeManagementClient

from azure.mgmt.network import NetworkManagementClient

from azure.mgmt.resource import ResourceManagementClient




def create_vm_with_docker(resource_group, vm_name, location, subscription_id, client_id, client_secret, tenant_id):

    # Authenticate using service principal

    credential = ClientSecretCredential(client_id=client_id, client_secret=client_secret, tenant_id=tenant_id)

    # Initialize management clients

    resource_client = ResourceManagementClient(credential, subscription_id)

    compute_client = ComputeManagementClient(credential, subscription_id)

    network_client = NetworkManagementClient(credential, subscription_id)

    # Assuming network setup, storage, etc. are in place

    # Fetch SSH public key

    with open("~/.ssh/id_rsa.pub", "r") as f:

        ssh_key = f.read().strip()

    # Define the VM parameters, including post-deployment script to install Docker

    vm_parameters = {

        #... (various VM parameters like size, OS type, etc.)

        'osProfile': {

            'computerName': vm_name,

            'adminUsername': 'azureuser',

            'linuxConfiguration': {

                'disablePasswordAuthentication': True,

                'ssh': {

                    'publicKeys': [{

                        'path': '/home/azureuser/.ssh/authorized_keys',

                        'keyData': ssh_key

                    }]

                }

            },

            'customData': "IyEvYmluL2Jhc2gKc3VkbyBhcHQtZ2V0IHVwZGF0ZSAmJiBzdWRvIGFwdC1nZXQgaW5zdGFsbCAt

            eSBkb2NrZXIuY2U="  # This is base64 encoded script for "sudo apt-get update && sudo apt-get install -y docker.ce"

        }

    }

    # Create VM

    creation_poller = compute_client.virtual_machines.create_or_update(resource_group, vm_name, vm_parameters)

    creation_poller.result()

    # Print the public IP address (assuming IP is already allocated)

    public_ip = network_client.public_ip_addresses.get(resource_group, f"{vm_name}-ip")

    print(f"Virtual Machine available at: {public_ip.ip_address}")

# Sample Usage (with parameters replaced appropriately)

# create_vm_with_docker(...)

Explanation:

The script begins by establishing authentication using the provided service principal credentials. It initializes management clients for resource, compute, and networking operations. After setting up networking and storage (which are assumed to be in place for brevity), the VM is defined with the necessary parameters. The post-deployment script installs Docker on the VM upon its first boot. Once the VM is created, its public IP address is printed.

Note: The Docker installation script is base64 encoded for brevity. In real use cases, you might use cloud-init or other provisioning tools for more complex setups.

5. Azure SQL Database: Data Migration and Querying

Azure SQL Database is a fully managed relational cloud database service for developers. The integration between applications and data becomes crucial, especially when migrating data or optimizing application performance through SQL queries.

Task: Write a Python script that does the following:

  1. Connects to an Azure SQL Database using provided connection details
  2. Migrates data from a CSV file into a table in the Azure SQL Database
  3. Runs a query on the table to fetch data based on specific criteria

Input Format: The script should accept command line arguments in the following order:

  • Connection string for the Azure SQL Database
  • Path to the CSV file
  • The query to run on the table

Constraints:

  • The CSV file will have headers that match the column names of the target table.
  • Handle exceptions gracefully, such as failed database connections, invalid SQL statements, or CSV parsing errors.

Output Format: The script should print:

  • A success message after data has been migrated
  • The results of the SQL query in a readable format

Sample Code:

import pyodbc

import csv

import sys

def migrate_and_query_data(conn_string, csv_path, sql_query):

    try:

        # Connect to Azure SQL Database

        conn = pyodbc.connect(conn_string)

        cursor = conn.cursor()

        # Migrate CSV data

        with open(csv_path, 'r') as file:

            reader = csv.DictReader(file)

            for row in reader:

                columns = ', '.join(row.keys())

                placeholders = ', '.join('?' for _ in row)

                query = f"INSERT INTO target_table ({columns}) VALUES ({placeholders})"

                cursor.execute(query, list(row.values()))

        print("Data migration successful!")

        # Execute SQL query and display results

        cursor.execute(sql_query)

        for row in cursor.fetchall():

            print(row)

        conn.close()

    except pyodbc.Error as e:

        print(f"Database error: {e}")

    except Exception as e:

        print(f"An error occurred: {e}")

# Sample usage (with parameters replaced appropriately)

# migrate_and_query_data(sys.argv[1], sys.argv[2], sys.argv[3])

Explanation: 

This script utilizes the `pyodbc` library to interact with Azure SQL Database. The script starts by establishing a connection to the database and then iterates through the CSV rows to insert them into the target table. After the data migration, it runs the provided SQL query and displays the results. The script ensures that database-related errors, as well as other exceptions, are captured and presented to the user.

Note: Before running this, you’d need to install the necessary Python packages, such as `pyodbc` and ensure the right drivers for Azure SQL Database are in place.

6. Azure Logic Apps with ARM Templates: Automated Data Sync

Azure Logic Apps provide a powerful serverless framework to integrate services and automate workflows. While the Azure Portal offers a user-friendly visual designer, in professional settings, especially with DevOps and CI/CD pipelines, there’s often a need to define these workflows in a more programmatic way. Enter ARM (Azure Resource Manager) templates: a declarative syntax to describe resources and configurations, ensuring idempotent deployments across environments.

Task: Taking it up a notch from the visual designer, your challenge is to implement an Azure Logic App that automates the process of syncing data between two Azure Table Storage accounts using an ARM template. This will test both your familiarity with the Logic Apps service and your ability to translate a workflow into an ARM template.

Inputs:

  • Source Azure Table Storage connection details
  • Destination Azure Table Storage connection details

Constraints:

  • Your ARM template should define the Logic App, its trigger, actions, and any associated resources like connectors.
  • The Logic App should be triggered whenever a new row is added to the source Azure Table Storage.
  • Newly added rows should be replicated to the destination Azure Table Storage without any data loss or duplication.
  • Any failures in data transfer should be logged appropriately.

Sample ARM Template (simplified for brevity):

{

    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",

    "contentVersion": "1.0.0.0",

    "resources": [

        {

            "type": "Microsoft.Logic/workflows",

            "apiVersion": "2017-07-01",

            "name": "SyncAzureTablesLogicApp",

            "location": "[resourceGroup().location]",

            "properties": {

                "definition": {

                    "$schema": "...",

                    "contentVersion": "...",

                    "triggers": {

                        "When_item_is_added": {

                            "type": "ApiConnection",

                            ...

                        }

                    },

                    "actions": {

                        "Add_item_to_destination": {

                            "type": "ApiConnection",

                            ...

                        }

                    }

                },

                "parameters": { ... }

            }

        }

    ],

    "outputs": { ... }

}

Explanation:

Using ARM templates to define Azure Logic Apps provides a programmatic and version-controllable approach to designing cloud workflows. The provided ARM template is a basic structure, defining a Logic App resource and its corresponding trigger and action for syncing data between two Azure Table Storage accounts. While the ARM template in this question is simplified, a proficient Azure developer should be able to flesh out the necessary details.

To implement the full solution, candidates would need to detail the trigger for detecting new rows in the source table, the action for adding rows to the destination table, and the error-handling logic.

Cracking an AWS interview involves more than just knowing the ins and outs of S3 buckets or EC2 instances. While a deep understanding of these services is vital, you also need to demonstrate how to use AWS resources effectively and efficiently in real-world scenarios.

An AWS interview typically tests your understanding of core AWS services, architectural best practices, security, and cost management. You could be quizzed on anything from designing scalable applications to deploying secure and robust environments on AWS. The level of complexity and depth of these questions will depend largely on the role and seniority level you are interviewing for.

AWS skills are not restricted to roles like cloud engineers or AWS solutions architects. Today, full-stack developers, DevOps engineers, data scientists, machine learning engineers, and even roles in management and sales are expected to have a certain level of familiarity with AWS. For instance, a full-stack developer might be expected to know how to deploy applications on EC2 instances or use Lambda for serverless computing, while a data scientist might need to understand how to leverage AWS’s vast suite of analytics tools.

That being said, irrespective of the role, some common themes generally crop up in an AWS interview. These include AWS’s core services like EC2, S3, VPC, Route 53, CloudFront, IAM, RDS, and DynamoDB; the ability to choose the right AWS services based on requirements; designing and deploying scalable, highly available, and fault-tolerant systems on AWS; data security and compliance; cost optimization strategies; and understanding of disaster recovery techniques.

1. Upload a File to S3

Amazon S3 (Simple Storage Service) is one of the most widely used services in AWS. It provides object storage through a web service interface and is used for backup and restore, data archiving, websites, applications, and many other tasks. In a work environment, a developer may need to upload files to S3 for storage or for further processing. Writing a script to automate this process can save a significant amount of time and effort, especially when dealing with large numbers of files. 

Task: Write a Python function that uploads a file to a specified S3 bucket.

Input Format: The input will be two strings: the first is the file path on the local machine, and the second is the S3 bucket name.

Output Format: The output will be a string representing the URL of the uploaded file in the S3 bucket.

Sample Code:

import boto3

def upload_file_to_s3(file_path, bucket_name):

    s3 = boto3.client('s3')

    file_name = file_path.split('/')[-1]

    s3.upload_file(file_path, bucket_name, file_name)

    file_url = f"https://{bucket_name}.s3.amazonaws.com/{file_name}"

    return file_url

Explanation:

This question tests a candidate’s ability to interact with AWS S3 using Boto3, the AWS SDK for Python. The function uses Boto3 to upload the file to the specified S3 bucket and then constructs and returns the file URL.

2. Launch an EC2 Instance

Amazon EC2 (Elastic Compute Cloud) is a fundamental part of many AWS applications. It provides resizable compute capacity in the cloud and can be used to launch as many or as few virtual servers as needed. Understanding how to programmatically launch and manage EC2 instances is a valuable skill for developers working on AWS, as it allows for more flexible and responsive resource allocation compared to manual management. 

Task: Write a Python function using Boto3 to launch a new EC2 instance.

Input Format: The input will be two strings: the first is the instance type, and the second is the Amazon Machine Image (AMI) ID.

Output Format: The output will be a string representing the ID of the launched EC2 instance.

Sample Code:

import boto3

def launch_ec2_instance(instance_type, image_id):

    ec2 = boto3.resource('ec2')

    instances = ec2.create_instances(

        ImageId=image_id,

        InstanceType=instance_type,

        MinCount=1,

        MaxCount=1

    )

    return instances[0].id

Explanation:

The function uses Boto3 to launch an EC2 instance with the specified instance type and AMI ID, and then returns the instance ID. This intermediate-level question tests a candidate’s knowledge of AWS EC2 operations.

3. Read a File from S3 with Node.js

Reading data from an S3 bucket is a common operation when working with AWS. This operation is particularly important in applications involving data processing or analytics, where data stored in S3 needs to be loaded and processed by compute resources. In this context, AWS Lambda is often used for running code in response to triggers such as changes in data within an S3 bucket. Therefore, a developer should be able to read and process data stored in S3. 

Task: Write a Node.js AWS Lambda function that reads an object from an S3 bucket and logs its content.

Input Format: The input will be an event object with details of the S3 bucket and the object key.

Output Format: The output will be the content of the file, logged to the console.

Sample Code:

const AWS = require('aws-sdk');

const s3 = new AWS.S3();

exports.handler = async (event) => {

    const params = {

        Bucket: event.Records[0].s3.bucket.name,

        Key: event.Records[0].s3.object.key

    };

    const data = await s3.getObject(params).promise();

    console.log(data.Body.toString());

};

Explanation:

This advanced-level question requires knowledge of AWS SDK for JavaScript (in Node.js) and Lambda. The above AWS Lambda function is triggered by an event from S3. The function then reads the content of the S3 object and logs it. 

4. Write to a DynamoDB Table

Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It’s commonly used to support web, mobile, gaming, ad tech, IoT, and many other applications that need low-latency data access. Being able to interact with DynamoDB programmatically allows developers to build more complex, responsive applications and handle data in a more flexible way.

Task: Write a Python function using Boto3 to add a new item to a DynamoDB table.

Input Format: The input will be two strings: the first is the table name, and the second is a JSON string representing the item to be added.

Output Format: The output will be the response from the DynamoDB put operation.

Sample Code:

import boto3

import json

def add_item_to_dynamodb(table_name, item_json):

    dynamodb = boto3.resource('dynamodb')

    table = dynamodb.Table(table_name)

    item = json.loads(item_json)

    response = table.put_item(Item=item)

    return response

Explanation:

This function uses Boto3 to add a new item to a DynamoDB table. The function first loads the item JSON string into a Python dictionary, then adds it to the DynamoDB table. This question tests a candidate’s knowledge of how to interact with a DynamoDB database using Boto3.

5. Delete an S3 Object

Being able to delete an object from an S3 bucket programmatically is important for maintaining data hygiene and managing storage costs. For instance, you may need to delete objects that are no longer needed to free up space and reduce storage costs, or you might need to remove data for compliance reasons. Understanding how to perform this operation through code rather than manually can save a lot of time when managing large amounts of data.

Task: Write a Node.js function to delete an object from an S3 bucket.

Input Format: The input will be two strings: the first is the bucket name, and the second is the key of the object to be deleted.

Output Format: The output will be the response from the S3 delete operation.

Sample Code:

const AWS = require('aws-sdk');

const s3 = new AWS.S3();

async function delete_s3_object(bucket, key) {

    const params = {

        Bucket: bucket,

        Key: key

    };
    const response = await s3.deleteObject(params).promise();

    return response;
}

Explanation:

The function uses the AWS SDK for JavaScript (in Node.js) to delete an object from an S3 bucket and then returns the response. This expert-level question tests the candidate’s ability to perform S3 operations using the AWS SDK.

With a seemingly endless array of platforms and services, cloud computing is democratizing technology, breaking down barriers to entry, and enabling innovation at an unprecedented scale. From scrappy startups leveraging scalability to Fortune 500 companies streamlining their operations, cloud computing is not just a tool – it’s the new normal.

Yet, despite the sweeping changes it has already brought, cloud computing is not static. It continues to evolve, driven by relentless technological advancement and ever-changing business needs. So where’s it headed next? And what does the future of cloud computing look like? These are not just questions for tech enthusiasts, but crucial considerations for anyone involved in the technology industry — whether you’re a hiring manager scouting for top talent or a professional looking to ride the next big wave.

#1. AI and ML Become More Embedded in Cloud Computing

The synergy between machine learning (ML) and cloud computing is more than a marriage of convenience. It’s a powerful partnership that’s redefining what’s possible in AI.

AI and ML, known for their data-hungry nature, are no longer confined to high-powered research labs and enterprises with the on-site resources to feed them. Today, these technologies are accessible to many, thanks to the vast data processing capabilities and virtually limitless storage offered by cloud computing. According to a recent report by Red Hat, 66% of organizations deploy their AI and ML models using a hybrid cloud strategy, with another 30% of companies using only cloud infrastructure to power their models. 

This fusion has brought us AI-powered chatbots that offer personalized customer service, real-time fraud detection systems that safeguard our online transactions, and advanced predictive models that provide invaluable business insights, to name a few.

Cloud-based AI and ML are also enhancing automation within cloud systems themselves. For instance, AI can be used to automate routine administrative tasks, such as resource provisioning and load balancing, reducing human error and improving operational efficiency. 

Furthermore, AI and ML are pushing the boundaries in cloud security. Machine learning algorithms can be trained to detect unusual behavior or anomalies in network traffic, flagging potential threats before they become full-blown security incidents. According to Capgemini, 69% of organizations believe that they can’t respond to critical threats without AI.

In short, AI and ML are not just adding bells and whistles to cloud computing — they’re deeply woven into the fabric of this technology, pushing its capabilities to new heights. The potential is enormous, and we’re only scratching the surface of this game-changing trend. 

#2. Investment in Cloud Security Becomes a Must

As cloud computing becomes a dominant force in the IT landscape, securing these cloud platforms is becoming a paramount concern. Per a recent report, the cloud security market size is projected to grow from $40.8 billion in 2022 to $77.5 billion by 2026, almost doubling in just four years. This trend clearly underscores the growing focus and investment on cloud security by organizations of all sizes and industries.

Cloud security is not a single monolithic entity though; rather, it is a collection of multiple security protocols, tools, and strategies designed to protect data, applications, and the infrastructure of cloud computing. It covers areas like data privacy, compliance, identity and access management, and protection against threats like data breaches, DDoS attacks, and malware.

One of the key reasons behind this increased investment is the rise in sophisticated cyber threats, which increased by 38 percent in 2022. As technology advances, so does the cunning and capability of cybercriminals. A single security breach can lead to significant financial loss and damage to an organization’s reputation, making it crucial for organizations to stay one step ahead.

Further, the shift toward remote working has amplified the need for robust cloud security. With employees accessing sensitive company data from various locations and often on personal devices, the potential for security vulnerabilities has increased. In this context, cloud security tools and protocols play a critical role in safeguarding data and maintaining business continuity.

Moreover, regulatory requirements are also driving investment in cloud security. Regulations like GDPR in Europe and CCPA in California demand stringent data security measures from organizations, pushing them to invest more in securing their cloud platforms.

Looking ahead, expect cloud security to remain a top priority for organizations in 2023 and beyond. As more data and processes migrate to the cloud, we’ll see a continued focus on developing advanced security strategies, tools, and best practices to protect these virtual environments.

#3. Multi-Cloud and Hybrid Strategies Become Standard

In the early days of cloud computing, many organizations found themselves tied to a single cloud provider, often finding themselves locked into their services. As the industry evolved, these organizations came to the realization that a “one-size-fits-all” approach did not cater to the diverse needs of their businesses. This realization gave birth to multi-cloud and hybrid cloud strategies, a trend that is gathering speed in 2023.

According to the Flexera 2023 State of the Cloud Report, 87% of enterprises have a multi-cloud strategy, while 72% have a hybrid cloud strategy. But what’s driving this shift toward using multiple cloud vendors and a blend of private and public clouds?

One key factor is avoiding vendor lock-in. By distributing workloads across multiple providers, companies gain more flexibility and reduce the risk of being too reliant on a single provider. It also allows companies to leverage the best features and services from different providers, creating an IT environment tailored to their specific needs.

Moreover, multi-cloud and hybrid strategies can also enhance operational resilience. By not having all their eggs in one basket, companies can mitigate the risk of a single point of failure. If there’s a service disruption in one cloud, they can ensure business continuity by relying on their other cloud environments.

Container technologies like Kubernetes and Docker play a pivotal role in realizing the benefits of multi-cloud and hybrid strategies. Kubernetes, an open-source container orchestration tool, helps manage workloads across multiple clouds, ensuring they interact seamlessly. Docker, on the other hand, simplifies the creation and deployment of applications within containers, making them portable across different cloud environments.

These tools support the implementation of a multi-cloud or hybrid cloud strategy by making it easier to move workloads across different clouds and ensuring they operate consistently, regardless of the underlying infrastructure.

In 2023, the shift towards multi-cloud and hybrid cloud strategies is expected to continue. As businesses strive for agility, operational resilience, and best-in-class services, a diversified approach to cloud computing seems to be the way forward.

#4. Industry-Specific Cloud Adoption Grows

Every industry has its unique needs and challenges, and the one-size-fits-all approach of the early cloud days is evolving to accommodate these specifics. In 2023, one of the significant cloud computing trends is the rise of industry-specific cloud solutions, often termed as industry clouds. According to a recent Gartner survey among North American and European-based enterprises, nearly 40% of respondents had started the adoption of industry cloud platforms, with another 15% in pilots and an additional 15% considering deployment by 2026.

But what exactly are industry clouds, and why are they gaining traction? Industry clouds are cloud services and solutions tailored to the needs of a specific industry — like healthcare, finance, manufacturing, or retail. These clouds come equipped with industry-specific features and compliance measures, making them ready-to-use platforms for businesses within that industry.

For instance, cloud solutions designed for the healthcare industry — such as Microsoft Cloud for Healthcare and CareCloud — come with features to support electronic health records, telemedicine, and medical imaging. These platforms also comply with healthcare regulations like HIPAA, making it easier for healthcare providers to adopt and use these solutions without fretting over compliance issues.

This industry-specific approach has multiple benefits. Firstly, it reduces the need for extensive customization — businesses get a platform that is already attuned to their needs, helping them get started faster. Secondly, it reduces the compliance burden, especially in heavily regulated industries like healthcare and finance. Finally, it brings industry-specific innovations to the table — like AI-powered risk assessments in finance or remote patient monitoring in healthcare, enhancing the capabilities of businesses within those industries.

The growing adoption of industry clouds is a testament to the maturing cloud computing market, where customization and specialization are playing an increasingly important role. This trend not only brings the benefits of cloud computing to more businesses but also fosters innovation within industries, making it a trend to watch in 2023.

#5. Cloud-Native Architecture Matures

As more businesses embrace the cloud, there’s a growing trend toward building applications that are native to this environment, known as cloud-native architecture. According to the Cloud Native Computing Foundation’s 2022 survey, 44% of respondents stated they’re already using containers for nearly all applications and business segments and another 35% said they use containers for at least a few production applications. Given that containers are often a key component of cloud-native applications, these numbers indicate a substantial shift toward cloud-native technologies.

But why the surge in interest? Cloud-native architecture provides several key advantages over traditional application development. 

Firstly, it offers exceptional scalability. Cloud-native applications are built around microservices, which are individual, loosely coupled services that make up a larger application. This means individual components can be scaled up or down based on demand, allowing for efficient use of resources.

Secondly, cloud-native architecture is designed with resilience in mind. Given the distributed nature of microservices, if one service fails, it does not bring down the entire application. This design aids in achieving higher application uptime and a better user experience.

Thirdly, it fosters faster innovation and reduces time to market. With microservices, teams can work on different services independently, making updates or adding new features without waiting for a full application release.

The rise of cloud-native architecture is intertwined with open source and serverless computing. Open-source projects like Kubernetes and Docker have been instrumental in accelerating the adoption of cloud-native architectures, providing the necessary tools to manage and orchestrate containers.

On the other hand, serverless computing takes the cloud-native approach a step further by abstracting away even the infrastructure layer. Developers just need to write code, and the cloud provider takes care of the rest — from managing servers to scaling. This allows developers to focus solely on coding and delivering value, making serverless computing a significant player in the rise of cloud-native.

As we navigate through 2023, we can expect to see a continued surge in cloud-native architecture as businesses strive to make the most of their cloud investments. With its promise of scalability, resilience, and speed, cloud-native is the new frontier in cloud computing.

#6. Quantum Computing Becomes Democratized

If you’ve been keeping an eye on technology trends, you’ve likely heard whispers — and perhaps a few loud proclamations — about quantum computing. This exciting field promises to redefine what’s possible in computing, solving complex problems that would take traditional computers thousands of years to crack.

But quantum computers are expensive and challenging to maintain, putting them out of reach for most businesses. That’s where cloud computing comes into play. The intersection of quantum computing and cloud services has emerged as a significant trend in 2023, democratizing access to quantum computing capabilities. A report by MarketsandMarkets projected the global cloud-based quantum computing services market to grow from an estimated $798 million in 2023 to $4.06 billion by 2028.

Several tech giants, including IBM, Google, and Microsoft, offer cloud-based quantum computing services, allowing businesses to run quantum algorithms without owning a quantum computer. These cloud-based quantum platforms also provide developers with the tools to experiment with quantum programming and develop quantum software applications.

But quantum computing in the cloud isn’t just about granting access to quantum machines. It’s also about integrating quantum capabilities with classical computing resources. Hybrid quantum-classical algorithms, where a classical computer and a quantum computer work in tandem, offer exciting possibilities. For instance, a quantum processor could handle computationally intensive tasks, while a classical computer manages other parts of the algorithm, optimizing the use of resources.

The trend of quantum computing in the cloud holds enormous potential. While it’s still in the nascent stages, with quantum technology becoming more mature and accessible, businesses of all sizes will start to explore quantum solutions for their most complex problems.

This integration of quantum computing capabilities into the cloud environment signifies a significant leap forward in computing and is a trend worth watching in 2023 and beyond. It might not be long before quantum cloud services become a standard offering alongside the familiar classical cloud resources.

#7. Cloud FinOps Addresses Rising Costs

As organizations scale their cloud operations, managing and optimizing cloud costs become increasingly complex yet critical tasks. This is where cloud financial management, or cloud FinOps, comes into play. In a survey of over 1,000 IT decision makers, HashiCorp-Forrester reported that 94% of respondents said their organizations had notable, avoidable cloud expenses due to a combination of factors such as underused and overprovisioned resources, and a lack of skills to utilize cloud infrastructure.

Cloud FinOps is a practice designed to bring financial accountability to the variable spend model of the cloud, enabling organizations to get the most business value out of each cloud dollar spent. In essence, it’s all about understanding and controlling cloud costs while maximizing the benefits.

Cost optimization is the primary driver behind FinOps. Unlike traditional IT purchasing, where costs are typically fixed and capital-based, cloud costs are operational and can fluctuate based on usage. This means that poorly managed resources can lead to cost overruns and wasted spend. 

FinOps practices help organizations forecast and track cloud spending, allocate costs to the right departments or projects, and identify opportunities for cost savings. This might involve rightsizing resources, selecting the right pricing models (like choosing between on-demand, reserved, or spot instances), or identifying and eliminating underused or orphaned resources.

Importantly, FinOps is not just a finance or IT function — it’s a cross-functional practice that brings together technology, business, and finance teams to make collaborative, data-driven decisions about cloud usage and spend. 

As businesses rely more on the cloud, cloud FinOps will continue to grow in importance. In fact, the FinOps Foundation research indicates that 60 to 80 percent of organizations are building FinOps teams.

Going forward in 2023, expect cloud FinOps to become a standard practice for organizations seeking to align their cloud investments with business objectives. As the saying goes, “You can’t manage what you can’t measure,” and cloud FinOps provides the tools and practices needed to measure — and hence manage — cloud costs effectively.

#8. Edge Computing Complements the Cloud

If you think the story of cloud computing is all about centralized data centers, think again. One of the most exciting cloud computing trends in 2023 is the rise of edge computing, a market that’s expected to reach an estimated $74.8 billion by 2028.

So, what is edge computing, and why is it so crucial to the future of cloud computing? 

Edge computing is a model where computation is performed close to the data source, i.e., at the “edge” of the network, instead of being sent to a centralized cloud-based data center. This drastically reduces latency and bandwidth usage, as less data needs to be sent over the network.

Consider a self-driving car. It generates enormous amounts of data that need to be processed in real time to make split-second decisions. Sending this data to a cloud data center and waiting for a response isn’t practical due to latency. With edge computing, this data can be processed on the vehicle itself or a nearby edge server, enabling real-time decision making.

But this doesn’t mean edge computing is replacing cloud computing. Far from it. Instead, edge computing complements cloud computing, forming a powerful combination that brings together the best of both worlds. The edge can handle time-sensitive data, while the cloud takes care of large-scale computation, storage, and less time-sensitive tasks.

The rise of IoT devices and the rollout of 5G are key drivers of this trend. As these devices proliferate and 5G reduces network latency, edge computing becomes increasingly viable and necessary.

In 2023, expect to see more businesses integrating edge computing into their cloud strategies. This combination of localized data processing with the computational power of the cloud paves the way for innovative applications, from autonomous vehicles to smart factories, reshaping the future of technology and business.

A Dynamic Cloud on the Horizon

In 2023, it’s clear that the cloud computing landscape is experiencing dynamic change and growth. The trends we’ve explored reflect a shift toward increased automation, resilience, cost-effectiveness, and versatility in the cloud. 

From the pervasive influence of AI and machine learning to the proliferation of multi-cloud and cloud-native strategies supported by powerful tools like Kubernetes and Docker, organizations are getting more sophisticated and efficient in how they use the cloud. 

These trends illustrate a cloud computing environment that’s maturing, diversifying, and becoming even more integral to our digital economy. As businesses, developers, and IT professionals, keeping a finger on the pulse of these trends is critical to harnessing the power of the cloud and driving innovation.

As a result, the demand for skilled cloud engineers has skyrocketed, with companies eagerly seeking individuals who can design, implement, and manage cloud-based solutions that meet their unique needs.

The pace of innovation in the cloud shows no signs of slowing down either, with new tools and services being introduced on a regular basis. In fact, Gartner forecasts worldwide public cloud end-user spending to reach nearly $600 billion in 2023. As more companies shift to the cloud, the demand for cloud engineering skills continues to rise, making it crucial for tech professionals to stay up-to-date with the latest trends and technologies in the field. In this blog post, we’ll explore some of the most important cloud computing skills that will be in high demand in 2023, providing insights for both hiring managers and tech professionals alike.

Cloud Security

With more and more data being stored in the cloud, security is becoming a top priority for organizations, making this one of the most critical skills for cloud engineers to possess in 2023. As companies continue to move their operations to the cloud, they must ensure that their data and systems are secure from threats such as hacking, data breaches, and cyber attacks. Cloud security encompasses a range of best practices, technologies, and principles that are designed to protect cloud-based assets from these types of threats.

Key cloud security principles include:

  • Identity and access management, which ensures that access is only granted to authorized users
  • Data encryption, which is the process of encoding sensitive data to protect it from unauthorized access
  • Network security, which involves securing the communication channels between cloud-based assets and users; 
  • Threat management, which allows cloud engineers to monitor and respond to potential threats to cloud-based assets, such as malware or denial-of-service attacks.

Cloud engineers have a variety of tools and technologies at their disposal to manage security. This includes firewalls, intrusion detection systems, and security information and event management (SIEM) systems. Combined, these technologies help engineers prevent unauthorized access to cloud-based assets, monitor network traffic to identify potential threats, and collect and analyze security-related data from multiple sources, providing a comprehensive view of potential security issues.

Cloud Architecture

Cloud architecture, which refers to the design and structure of cloud-based systems, components, and services, is another essential skill for cloud engineers to have in 2023. 

Some of the key principles of cloud architecture include scalability, availability, reliability, and performance. These principles ensure that the cloud system is able to remain operational in the event of failures or disruptions, handle workloads efficiently, perform consistently over time, and handle increasing amounts of traffic or data without compromising performance.

To achieve these key principles, cloud architects design systems that make use of the appropriate cloud-based services and resources. These might include compute resources like virtual machines, storage resources like object storage or block storage, or networking resources like virtual private clouds or load balancers. Cloud architects must also ensure that these resources are configured and optimized to meet the needs of the system they are designing.

Some of the key cloud architecture technologies and tools cloud engineers should be familiar with include:

  • Infrastructure as code (IaC) tools, like Terraform
  • Containerization platforms, particularly platforms like Docker or Kubernetes
  • Serverless computing services, which allow developers to focus on writing code without worrying about underlying infrastructure.

Automation and Orchestration

As more companies move to the cloud, the complexity of cloud-based systems is increasing. This means that there are more moving parts to manage and deploy, which can be time-consuming and error-prone if done manually. Automation and orchestration skills are critical for managing these complexities. 

Cloud automation is the process of automating the deployment, scaling, and management of cloud-based systems. With cloud automation, tasks that would normally require manual intervention, such as provisioning servers or deploying code, can be automated, saving time and reducing the risk of human error.

Cloud orchestration takes this one step further by automating the management and coordination of complex cloud-based systems. With cloud orchestration, engineers can manage and coordinate the interactions between different cloud-based services and applications, making it easier to deploy and manage complex systems.

To become proficient in cloud automation and orchestration, engineers should have experience with scripting languages like Python or PowerShell, as well as knowledge of configuration management tools like Ansible or Puppet. Familiarity with cloud-based orchestration tools like Kubernetes or Docker Swarm is also important.

Cloud Cost Optimization

As companies move to the cloud, they’re realizing the benefits of cost savings and scalability. However, as cloud usage increases, so do the costs. Cloud computing can be expensive, and if not managed properly, costs can quickly spiral out of control.

That’s where cloud cost optimization comes in. It’s the process of optimizing cloud costs to ensure that organizations get the most value out of their cloud investments. With cloud cost optimization, engineers can identify areas where costs can be reduced or eliminated, while still ensuring that cloud-based systems are meeting the needs of the organization.

One important cost optimization principle is the use of reserved instances or committed use contracts. These allow organizations to commit to a certain amount of cloud usage over a period of time, which can result in significant cost savings.

Another important principle is the use of autoscaling. Autoscaling allows organizations to automatically increase or decrease resources based on demand, ensuring that they’re only paying for what they need. This can result in significant cost savings, especially during periods of low demand.

Engineers should also be familiar with cloud cost management tools, such as AWS Cost Explorer or Google Cloud Billing. These tools can help engineers identify areas where costs can be reduced or eliminated, and provide insights into cloud usage patterns and trends.

To become proficient in cloud cost optimization, engineers should have a deep understanding of cloud usage patterns and trends, as well as a strong understanding of cloud pricing models and cost management tools. Familiarity with scripting languages like Python or PowerShell can also be helpful with optimizing costs.

Cloud Migration

Cloud migration is the process of moving data, applications, and other business elements from an organization’s on-premises infrastructure to the cloud. It involves several phases, including assessment, planning, execution, and optimization, and it requires an in-depth understanding of both the current infrastructure and the target cloud environment.

One of the most critical cloud migration skills is the ability to assess the current infrastructure and determine which applications and workloads are best suited for migration. The assessment phase involves analyzing various factors, such as data security requirements, regulatory compliance, and performance metrics. A cloud engineer with migration skills can also identify any potential issues that may arise during migration, such as compatibility issues, data loss, and service disruptions.

Once the assessment phase is complete, the cloud engineer can begin the planning phase. This phase involves developing a detailed migration plan that includes timelines, resource requirements, and a risk management strategy. Cloud engineers should be able to help organizations choose the right cloud provider, select the appropriate migration tools, and develop a strategy for testing and validating the migration plan.

The execution phase is where the actual migration takes place. Cloud engineers oversee the migration process, monitor progress, and troubleshoot any issues that arise. They should also provide regular updates to stakeholders, manage any change requests, and ensure that the migration is completed on time and within budget.

Cloud Analytics

Cloud analytics is an important skill for cloud engineers because it allows them to extract valuable insights and knowledge from the data collected by cloud-based applications and systems. With the ability to harness the power of data, organizations can optimize their operations, make data-driven decisions, and gain a competitive advantage.

To put it simply, cloud analytics refers to the process of collecting, analyzing, and interpreting data generated by cloud-based systems. This data can include user behavior, performance metrics, and usage patterns, among other things. With cloud analytics, organizations can use this data to monitor their systems, detect issues and anomalies, and identify opportunities for improvement.

Some of the key cloud analytics tools and technologies that cloud engineers should be familiar with include cloud-based data warehouses such as Amazon Redshift and Google BigQuery, data visualization tools such as Tableau and PowerBI, cloud-based machine learning tools such as Amazon SageMaker and Google Cloud AI Platform, big data technologies such as Hadoop and Spark, as well as machine learning and AI.

In addition to these tools and technologies, cloud engineers should also be familiar with data governance and privacy regulations. Ensuring that data is secure, compliant, and properly managed is critical in the cloud environment and an important piece of the analytics puzzle.

Collaboration and Communication

Collaboration and communication are crucial skills for cloud engineers. The ability to work with other team members, communicate ideas effectively, and provide feedback can make or break a project. Cloud engineers need to be able to explain complex technical issues to technical and non-technical stakeholders, work with cross-functional teams, and coordinate with various departments to ensure that projects are delivered on time and within budget. This requires effective communication skills, the ability to listen actively, and the capacity to work in a team environment.

In addition, cloud engineers need to be skilled at providing feedback to other team members. This feedback may include suggesting improvements, identifying issues, or proposing new ideas. The ability to provide constructive feedback in a way that is both clear and non-confrontational is an essential component of collaboration.

Effective communication skills are also critical when working with non-technical stakeholders, such as business leaders, customers, and vendors. Cloud engineers must be able to explain complex technical concepts in a way that is understandable to these stakeholders. This requires the ability to communicate in plain language, present information clearly, and listen actively.

Key Takeaways

As you can see, cloud computing skills are becoming increasingly important for tech professionals as the demand for cloud services continues to grow. To succeed in this field, cloud engineers need to have a diverse set of skills that go beyond just technical expertise.

Despite being less than two decades old, DevOps plays a vital role in the software development industry. Today, 77% of organizations rely on DevOps to deploy software. Unsurprisingly, this has led to DevOps engineer becoming the seventh most in-demand job in the world. In this post, we break down the statistics, job requirements, and responsibilities of a career in DevOps engineering.

What Is DevOps?

DevOps balances software development and IT operations to support continuous integration and continuous delivery (CI/CD). It’s a methodology with a goal to keep an entire organization working together seamlessly, with agile processes and systems. DevOps allows businesses to create and release updates to their services and products faster than traditional development models. When done well, this means you can deploy code multiple times daily.

What Does a DevOps Engineer Do?

A DevOps engineer is responsible for managing and maintaining code, application maintenance, as well as application management. They work with a variety of experts in different departments to coordinate the design, development, testing, release, and lifecycle management of software and applications.

A DevOps engineer is responsible for any number of tasks related to:

  • Project management
  • Writing, editing, and coordinating code and review
  • System performance testing and maintenance
  • Prototyping features and solutions
  • Server administration

What Kinds of Companies Hire DevOps Engineers?

Any company that creates software or applications needs DevOps engineers to manage their operations. With companies in every industry becoming increasingly driven by technology, the demand and opportunities for professionals with this skill set continues to grow. The top sectors employing DevOps engineers include:

  • Fortune 500: 29%
  • Technology: 17%
  • Finance: 12%
  • Retail: 8%
  • Professional Services: 6%
  • Telecommunication: 4%
  • Manufacturing: 4%
  • Insurance: 4%
  • Healthcare: 3%

Types of DevOps Engineer Positions

The titles DevOps engineers hold vary drastically, depending on their experience, education, and company. At the beginning of their career, a DevOps engineer will start out with an entry-level role, like junior DevOps engineer or DevOps engineer I. A new DevOps engineer usually works in one of these roles for one to three years.

From there, they’ll have the opportunity to move into more senior-level and specialized roles with hands-on engineering experience. DevOps engineering job titles include: 

  • DevOps software developer
  • DevOps engineer
  • DevOps evangelist
  • Automation architect
  • Cloud DevOps engineer
  • Senior DevOps engineer

While they spend several years honing their skills, their responsibilities expand to include taking ownership of projects, working independently in a team environment, and mentoring project team members.

After gaining more experience, a DevOps engineer often faces a crossroads in their career having to choose between a few paths. 

The first path is to pivot into people and team management functions. Hiring, mentoring, resource planning and allocation, strategy, and operations become a larger component of the responsibilities of DevOps professionals pursuing this career path. At the higher levels of an organization, these job functions might include:

  • DevOps engineering manager
  • Director of DevOps
  • Chief Information Officer (CIO)
  • Chief Technology Officer (CTO)

The second possible career path is to continue as an individual contributor. Many DevOps engineers opt to continue their careers as individual contributors, enjoying equally fulfilling careers and developing deeper technical expertise in various languages and frameworks.

The third possible career path is to transition out of DevOps into a related field, such as software development, business analysis, or product management. Because the responsibilities of DevOps intersect with multiple technical disciplines, DevOps engineers are well-positioned to transition to a career in a different field that interests them.

Salary Comparisons and Job Outlook

Estimates of the average annual salary for a DevOps engineer range from $99,527 to $128,387. An entry-level DevOps engineer can earn an average salary of $67,000 while a DevOps engineer later in their career (over 20 years of experience) can average $143,000 annually. This doesn’t factor in bonuses, stock options, and other cash incentives that can add to total compensation.

While we don’t have data on the growth rate of DevOps engineers specifically, the U.S. Bureau of Labor Statistics does include this role in its overall data for software developers. Software developer employment is projected to grow 25 percent through 2031 — more than triple the average for all occupations.

Requirements to Become a DevOps Engineer

Technical Skills

DevOps engineers use a range of programming languages to deliver software. These include, to name a few:

  • Python
  • Java
  • JavaScript
  • Go
  • PHP
  • PERL
  • Ruby
  • TypeScript

A core requirement of DevOps is expertise in the technologies offered by cloud-hosting providers. These include, to name a few:

  • AWS
  • Azure
  • GCP
  • IBM Cloud
  • Oracle Cloud

Typically, DevOps engineers are expected to have familiarity with a wide range of development tools, including:

DevOps is a constantly evolving field, so it’s important to do research specific to the industries and roles you’re applying to or hiring for to understand specific technical competencies.

Soft Skills

Technical competency alone isn’t enough to succeed in a DevOps engineering role. Analytical, mathematical, and problem-solving skills are a must in any technical job. And in a digital-only or remote first environment, soft skills are even more critical.

Employers may prefer engineers with strong soft skills, such as:

  • Problem solving
  • Communication
  • Project management
  • Time management
  • Creativity

Experience

After technical skills, the most important qualification for DevOps engineers is experience. On-the-job experience and training is a critical requirement for many employers.

Then, there’s the question of education. The education requirements for DevOps positions vary widely. In the U.S., the vast majority of DevOps engineers have a college education, with 75% having a bachelor’s degree, and 20% having a master’s. 

Many companies still require developers to have a four-year degree. While hiring developers, it’s likely that many of them will have a degree. However, competition for skilled software engineers is high, and it’s not uncommon for job openings with a degree requirement to go unfilled. Ultimately, employers that prioritize real-world skills over pedigree gain access to a larger volume of skilled DevOps talent.

In 2021, the size of the global cloud computing market was valued at $445.3 billion. And it’s expected to grow to $947.3 billion by 2026. That’s a blistering growth rate of 112.7 percent in just five years.

However, the tech industry is facing a huge deficit in the number of skilled cloud engineers available to build this growing industry. If left unchecked, this hiring gap could hinder the growth and innovation of the cloud computing industry writ large. 

In this post, we’ll break down the statistics, job requirements, and responsibilities of a career in cloud engineering.

Overview of the Duties of a Cloud Engineer

Companies of every size and industry are racing to the cloud. Cloud computing is a service that provides on-demand access to computer system resources without direct management or ownership by the party using the service. These services include computing power, data storage, platforms, infrastructure, and software.

Cloud engineers are IT professionals responsible for a company’s cloud computing infrastructure, including design, implementation, maintenance, and support.

Cloud engineers will work in a variety of cloud environments, including Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

On a more technical level, the core job responsibilities of cloud engineers include:

  • Writing highly scalable, testable code
  • Building cloud environments on cloud infrastructure platforms
  • Configuring cloud infrastructure components including networking and security services
  • Discovering and fixing programming bugs
  • Presenting and demonstrating features to internal and external stakeholders
  • Keeping up-to-date with advancements in technology
  • Working in an agile environment

What Kinds of Companies Hire Cloud Engineers?

Any company that’s looking to build cloud infrastructure or migrate their existing systems to the cloud will need to hire cloud engineers. As companies of every size transition to the cloud, the industries that cloud engineers work in continue to expand.

This trend was already well underway, but it was dramatically accelerated by the COVID-19 pandemic and prolonged global lockdowns. Overnight, a majority of the world’s work, education, and entertainment shifted online, leading to a dramatic spike in the demand for platforms, databases, and technologies supported by the cloud. This has left many companies struggling to find the cloud engineers they need to scale in a remote-first world. 

Retail, entertainment, software, consulting, financial services, defense, education, fintech, telecommunications, healthcare — the demand (and opportunity) for cloud engineering is nearly endless. 

In addition to the companies hiring engineers for their in-house teams, Microsoft, Amazon, and Google employ thousands of cloud engineers to work on their infrastructure as a service (IaaS), platform as a service (PaaS), and serverless computing environments.

Unsurprisingly, this growth in the demand and applications for cloud computing has had a direct impact on company hiring needs and the career outlook of cloud engineering.

In 2020, there were 775,022 cloud computing jobs posted, up 94% from 400,500 jobs posted just three years earlier. In comparison, all tech job postings grew around 20% during that period. That means the demand for cloud computing and engineering talent is growing nearly five times faster than the rest of the tech industry. 

It’s no understatement to say this explosion of cloud engineering demand has created one of the biggest talent needs in the tech industry.

This gap between supply and demand has had a direct impact on the companies unable to meet their hiring needs, keeping many businesses out of the cloud. As the cloud computing industry continues to grow, competition for great cloud talent is fierce and will be for the foreseeable future.

Types of Cloud Engineer Positions

The titles cloud engineers hold vary drastically, depending on their experience, education, and the company they work at. The title of a graduate from a coding bootcamp might look different than a candidate with a four-year degree. And the role of a cloud engineer in a five-person startup will be different than at a 5,000 person company.

At the beginning of their career, a cloud engineer will start out with an entry-level role, like Cloud Engineer I or Junior AWS Engineer. New cloud engineers will typically start their careers by working on internal or external project solutions along with systems and integration testing. They can expect to work in one of these roles for one to three years.

From there, they’ll have the opportunity to move into more senior-level roles with hands-on engineering experience, such as: 

  • Senior Cloud Engineer
  • Cloud Engineer II
  • Cloud Engineering Manager
  • Cloud Security Engineer
  • Senior AWS Engineer
  • Systems Engineer
  • Cloud Developer
  • Cloud Architect
  • Network Engineer

While they spend several years honing their skills, their responsibilities expand to include taking ownership of projects, working independently in a team environment, and mentoring project team members. Senior cloud engineers might also choose to specialize in a particular technology or discipline, such as cloud security or DevOps.

With some experience under their belt, a cloud engineer often faces a crossroads in their career having to choose between two paths. 

The first path is to pivot into people and team management functions. Hiring, mentoring, resource planning and allocation, strategy, and operations become a larger component of the responsibilities of cloud engineers pursuing this career path. At the higher levels of an organization, these titles include:

  • Director of Cloud Networking
  • Cloud Operations Manager
  • Director of Solutions Architecture
  • Chief Information Officer (CIO)
  • Chief Technology Officer (CTO)

The second possible career path is to continue as an individual contributor. Many cloud engineers opt to continue their careers as individual contributors, enjoying equally fulfilling careers and developing deeper technical expertise in various languages and frameworks.

The motivation behind this decision is that experienced cloud engineers aren’t necessarily interested in or qualified to be managing a team. And an engineer in an individual contributor role has the opportunity to focus on growing their technical skills and learning the newest emerging technologies.

Data is scarce on how this career decision will impact long-term earning potential. Career outlook for individual contributors and managers will also depend on a number of other factors, including industry, company size, and experience.

Salary Comparisons & Job Outlook

On average, cloud engineers tend to receive a salary significantly higher than the national average in their country.

For example, in the U.S. the average salary in 2020 was $53,400. In contrast, the average base salary for cloud engineers in the U.S. is $114,323 to $130,977. That’s 114 to 145 percent more than the national average.

Junior cloud engineers can expect to occupy a lower salary band at the beginning of their careers. In contrast, senior positions provide a higher average compensation, though data for this specific salary band is hard to find. Industry and company size also affect the salary band dramatically. Historically, though, geography has had a significant impact on the compensation of technical talent — and that includes cloud engineers. 

Cloud Engineering Skills

Technical Skills

Cloud engineers use a range of technologies to build cloud-based platforms, infrastructure, and applications. 

A core requirement of cloud engineering is expertise in the technologies offered by cloud-hosting providers. These include, to name a few:

  • AWS
  • Azure
  • GCP
  • IBM Cloud
  • Oracle Cloud

Recruiters and hiring managers who are hiring cloud engineers should look for in-demand competencies with the specific services and products offered by these platforms. An AWS cloud engineer, for example, might be familiar with Amazon cloud products such as Glue, Lake Formation, Redshift, Athena, MSK, and Kinesis.

Many cloud engineering roles require knowledge of data-oriented and object-oriented languages such as Java, Ruby, Python, or Clojure. Some roles also require familiarity with a general programming language, such as C, C+, C#, or Go. 

Depending on the role, software engineers might also work with a number of other tools:

  • Databases (SQL, MySQL, NoSQL)
  • Message brokers (RabbitMQ, ActiveMQ, Kafka)
  • Big data frameworks (Apache Hadoop, Apache Spark)
  • Familiarity with web services and APIs:
    • XML (Extensible Markup Language)
    • SOAP (Simple Object Access Protocol)
    • WSDL (Web Services Description Language)
    • UDDI (Universal Description, Discovery and Integration)

Some cloud engineers will specialize in DevOps, a set of practices that combines software development and IT operations. Core DevOps skills include:

Security and Compliance

Some cloud engineers specialize in keep computing resources and data secure, operational, and compliant. Cloud cybersecurity engineers typically need an understanding of cloud cybersecurity to create cloud backup strategies in preparation for outages, natural disasters, and cyberattacks. They also need the skills to identify regulations and guidelines for compliance.

Soft Skills

Technical competency alone isn’t enough to succeed in a cloud engineering role. Mathematical, analytical, and problem-solving skills are a must in any technical role. And soft skills are even more critical in a digital-first or digital-only environment.

Employers may put even more stock into engineers with strong soft skills, such as:

  • Time management
  • Communication
  • Project management
  • Problem solving

Communication skills, in particular, are critical to cloud engineering. Cloud engineers often work in client-facing or consulting roles that require them to communicate complex information to stakeholders in other departments or companies. The ability to turn technical subject matter into easy-to-understand solutions is highly valuable to cloud engineers — and the teams that employ them.

Certifications

All of the major cloud providers offer certification courses to cloud engineers, including AWS, Azure, and GCP. In addition to providing training in the platforms, certifications also serve as a credential for cloud engineers. For roles requiring experience with cloud providers, having a certification in the appropriate platform is a mandatory or nice-to-have qualification. 

Experience & Education

After competency, the most important qualification for cloud engineers is experience. On-the-job experience and training is a critical requirement for many employers.

Then, there’s the question of education. The education requirements for cloud engineering positions vary widely. Many employers still require cloud engineering candidates to have four-year degrees. Some might even expect graduate-level degrees.

But competition for skilled cloud engineers is fierce, and it’s common for job openings requiring degrees to go unfilled. There are simply not enough engineers with degrees to fill thousands of open roles out there. Companies looking to hire cloud engineers will have access to a much larger pool of talent and achieve their cloud initiatives if they recognize other forms of education and experience.
