• EC2 (Elastic Compute Cloud): Learn how to provision, configure, and manage virtual servers. See the EC2 Docs
• S3 (Simple Storage Service): Understand how to manage scalable object storage and secure data using encryption and policies. See the S3 Docs
• RDS (Relational Database Service): Experience with managing scalable, relational databases in the cloud. See the RDS Docs
• VPC (Virtual Private Cloud): This is critical for setting up isolated network environments, controlling inbound and outbound traffic, and ensuring network security. See the VPC docs
• CloudWatch: Monitoring resources and applications is essential. Familiarize yourself with setting up alarms, logs, and metrics. See the CloudWatch Docs
• IAM (Identity and Access Management): AWS uses IAM to manage access and control user permissions. A clear understanding of roles, users, and policies is critical for security and governance. See the IAM docs

2. Infrastructure as Code (IaC)

Modern cloud environments are heavily automated, so familiarity with Infrastructure as Code (IaC) is critical. AWS offers several tools to deploy, manage, and maintain infrastructure using code, which is more scalable and less error-prone than manual configuration. Key tools to master include:

• AWS CloudFormation: A native AWS service that lets you define infrastructure templates and automate the creation and management of resources. Getting Started with AWS CloudFormation Docs.

• Terraform: A widely-used tool in the industry that supports multiple cloud platforms, including AWS. Knowledge of how to write, maintain, and troubleshoot Terraform configurations is a big plus. Check the Terraform Tutorials.

• AWS CDK (Cloud Development Kit): Allows you to define AWS infrastructure in code using languages like Python, TypeScript, or Java. Getting Started CDK

Proficiency in these tools will help streamline resource management and make operations more efficient.

3. Linux and Scripting Skills

AWS runs heavily on Linux-based environments, so having hands-on experience with Linux is crucial. As an operations engineer, you'll need to handle tasks such as managing file systems, user permissions, process monitoring, and automation using shell scripts.

Additionally, you should be proficient in scripting languages such as Bash, Python, or PowerShell to automate repetitive tasks and develop quick fixes for operational issues. AWS’s own command-line interface (CLI) also plays a critical role in automation, and having the ability to write automation scripts will be an invaluable asset.

4. Networking and Security

Understanding networking principles is fundamental in AWS cloud operations. Some of the key networking skills you’ll need include:

• IP Addressing, Subnetting, and Routing: Knowing how to segment networks, route traffic, and connect to on-premise environments is essential for securing and maintaining the cloud infrastructure.
• Load Balancers and DNS (Route 53): Understanding how to distribute traffic using AWS's Elastic Load Balancer (ELB) and manage domain names with Route 53.
• Security Groups and Network Access Control Lists (NACLs): Know how to control traffic in and out of your VPCs, set up firewalls, and protect services.

Security is a top priority in cloud environments, so you’ll also need knowledge of best practices for:

• Encryption (at rest and in transit): Using AWS Key Management Service (KMS) to secure data.
• Compliance and Auditing: Familiarity with tools like AWS Config and CloudTrail to track resource configurations and audit access.
• Vulnerability Management: Implementing tools to identify and patch security vulnerabilities.

Take a look at the AWS Well-Architected Framework Security Pillar for details on AWS security best practices.

5. Automation and Monitoring

Automating operations and continuous monitoring are the backbone of efficient cloud operations. Your role will likely involve using various automation tools and creating self-healing systems that minimize manual intervention. Here are the tools and techniques to focus on:

• AWS Lambda: Serverless functions for automating tasks without needing dedicated servers. See the AWS Lambda Docs
• Automation via AWS Systems Manager: Automating routine tasks such as patching, backups, and configuration updates. See the AWS Systems Manager Docs
• AWS CloudWatch and CloudTrail: These services are essential for logging, auditing, and alerting. Master how to set up monitoring, trigger alarms, and automate responses based on system performance. See docs for AWS CloudTrail and the docs on setting up Amazon EventBride Rules.

For example, you might set up a CloudWatch alarm to monitor the CPU utilization of EC2 instances. If the utilization exceeds a defined threshold, you can trigger an automated scaling event or initiate a Lambda function to address the issue. CloudTrail helps with auditing changes to your AWS environment, enabling you to track all API activity.

6. Disaster Recovery and High Availability

Businesses rely on AWS for mission-critical services, so ensuring uptime and minimizing downtime is crucial. Familiarity with designing for high availability (HA) and disaster recovery (DR) is essential. Key concepts include:

• Multi-AZ Deployments: Ensure that your critical services, such as databases, run across multiple Availability Zones (AZs) to prevent single points of failure.
• Auto Scaling: Automatically adjust resources to handle load changes, minimizing costs while maintaining performance.
• Backup and Recovery Solutions: Understand how to set up automated backups, snapshot management, and restore processes using AWS services like AWS Backup and Amazon S3 Glacier for long-term storage.
• Cross-Region Replication: For disaster recovery, ensure data is replicated to different geographic regions to provide failover capabilities.

See the AWS Whitepaper on Disaster Recovery in the Cloud.

7. DevOps and CI/CD Pipelines

Cloud operations roles often overlap with DevOps practices, so having knowledge of Continuous Integration/Continuous Deployment (CI/CD) pipelines is an advantage. AWS provides several native tools for implementing DevOps methodologies:

• AWS CodePipeline: Automates the build, test, and deployment phases of applications. See AWS CodePipeline docs
• AWS CodeBuild and CodeDeploy: Facilitate building, testing, and deploying code changes to different environments. See the docs for AWS CodeBuild & AWS CodeDeploy
• Amazon ECR and ECS: If working with containerized applications, understanding AWS's Elastic Container Service (ECS) and Elastic Container Registry (ECR) is vital. See this Intro to Containers Guide

Experience with CI/CD tools allows you to build reliable pipelines that accelerate the development and deployment of cloud resources and applications.
