Infrastructure as code is a central principle of DevOps on AWS. CloudFormation remains the dominant tool, but the AWS Cloud Development Kit is rapidly gaining popularity. Both require not only basic understanding but also advanced knowledge of complex deployments.

With CloudFormation, you must be able to create nested stacks that allow large infrastructures to be broken down into smaller, reusable components. StackSets allow centralized deployment of resources across multiple accounts and regions, which is crucial for enterprises with distributed workloads. The exam often includes case studies where StackSets are the correct solution to multi-account management problems.

Parameters, mappings, and intrinsic functions are often tested in CloudFormation scenarios. You should also understand change sets and drift detection, which help manage and track modifications across stacks. Handling rollbacks gracefully when deployments fail is another advanced topic that appears in exam-style questions.

The Cloud Development Kit introduces infrastructure as code through familiar programming languages like Python, JavaScript, or TypeScript. Knowing how to leverage CDK constructs, synthesize templates, and deploy them provides flexibility that CloudFormation templates alone cannot offer. This skillset shows the ability to work with modern DevOps practices and is increasingly valuable to employers.

Monitoring and Observability in Detail

Monitoring is more than just setting up a few alarms. It involves creating a complete observability strategy that provides visibility across applications, infrastructure, and deployments.

CloudWatch metrics are powerful when used effectively. Custom metrics allow teams to monitor specific business indicators, such as order success rates or latency for critical endpoints. Alarms can trigger actions such as scaling or sending notifications, ensuring that systems respond automatically to changes. Dashboards provide a visual representation of system health, which is often important for both engineers and management teams.

Logs are just as critical. CloudWatch Logs Insights lets you run queries on massive log datasets, identifying anomalies or errors quickly. You should practice writing queries that filter by error codes, latency spikes, or user activity trends.

X-Ray adds another dimension by providing distributed tracing. It is particularly useful for microservices architectures where requests travel across multiple services.

Cross-account IAM roles often appear in exam scenarios. For example, you may be asked how to configure a pipeline in one account to deploy resources in another. The solution involves trust policies and role assumptions. These real-world use cases show the practical depth required.

Secrets management is equally important. AWS Secrets Manager and Parameter Store offer secure storage for credentials and configuration values. Learning how to integrate these with Lambda functions, ECS tasks, and CodeBuild projects ensures that sensitive data is never exposed in plain text.

Continuous Integration and Testing in AWS Pipelines

Continuous integration is a vital part of DevOps. In AWS, this process involves storing code in repositories, automatically building it, and running tests to verify functionality.

CodeCommit provides a secure, scalable Git-based repository. While you do not need to memorize every command, knowing how to integrate CodeCommit with CodePipeline and third-party tools is valuable.

CodeBuild handles testing at multiple levels. Unit testing ensures that small components of code function correctly, while integration testing checks how multiple components work together. Load and performance testing are also important, as AWS provides scalable environments to simulate traffic. The exam sometimes asks how to ensure performance requirements are met before deploying to production, and automated testing with CodeBuild is usually the correct answer.

Deployment Models and Strategies in AWS

Deployment strategies are one of the most tested areas in this certification. Blue green deployments allow seamless switching between old and new versions, reducing downtime. You should know how to configure Route 53 or Elastic Load Balancing to manage traffic between environments.

Rolling deployments are efficient for gradually replacing resources, ensuring that some capacity remains available at all times. Understanding how to set batch sizes, minimum healthy instances, and rollback policies is essential.

Canary deployments are also common in serverless and container-based environments. They allow small percentages of traffic to be directed to new versions, making it easier to identify issues before a full rollout. In the exam, you may encounter scenarios where the business wants to minimize risk while introducing new features, and canary deployment is often the correct solution.

Logging and Compliance Requirements in DevOps

Compliance is a constant concern in regulated industries. AWS CloudTrail provides a complete audit log of all API calls and changes. Engineers must understand how to enable CloudTrail across multiple accounts, configure log file encryption, and store logs in secure S3 buckets.

CloudWatch integrates with CloudTrail to provide insights and alarms on suspicious activities. For example, you may set up alerts when unusual API calls occur in an account.

Compliance also extends to GDPR, HIPAA, and PCI requirements. While the exam will not test legal details, it does expect you to know which AWS services help enforce compliance. Knowing how to implement encryption, secure storage, and least privilege access is critical for meeting compliance needs.

Automation with AWS Systems Manager

Systems Manager is one of the most versatile services for automating operational tasks. Its features range from patch management to secure access to instances.

Automation documents, also known as runbooks, provide repeatable workflows. For example, you can create an automation document that updates all EC2 instances with a new configuration. This reduces manual effort and ensures consistency.

Patch Manager keeps operating systems updated automatically. This is critical for security, and the exam may include scenarios where patch compliance is part of the solution.

Session Manager provides secure remote access to instances without the need for SSH keys or bastion hosts. Because it integrates with IAM and CloudTrail, it is both secure and auditable. Many organizations prefer Session Manager for compliance reasons, and the exam emphasizes its importance.

Scaling and High Availability in DevOps

Scalability is a major concern for modern applications. Auto Scaling Groups allow applications to adapt to changing demand. You should know how to configure scaling policies based on CloudWatch metrics such as CPU utilization or request count.

Elastic Load Balancing distributes traffic across multiple instances or containers. Understanding how to configure health checks and target groups is important. Application Load Balancers, Network Load Balancers, and Gateway Load Balancers each have unique use cases, and the exam may test your ability to select the right type.

Containers are increasingly common in DevOps workflows. ECS and EKS provide orchestration for containerized applications. Mastery here involves configuring task definitions, services, clusters, and scaling policies. EKS also introduces Kubernetes, which requires additional understanding of pods, nodes, and networking.

Disaster Recovery Planning and Implementation

Disaster recovery is another critical domain. AWS provides multiple strategies, each with different levels of cost and complexity.

Backup and restore is the simplest approach, where data is stored in S3 or Glacier and restored when needed. This is cost-effective but involves longer recovery times.

Pilot light keeps a minimal version of the system running in another region, ready to be scaled up in case of disaster. Warm standby involves a fully functional scaled-down version of the application that can quickly be scaled up. Multi-site active active provides the highest availability, with resources running in multiple regions simultaneously.

The exam often asks candidates to choose the best disaster recovery strategy for a given scenario, balancing cost and recovery time objectives.

Security Automation for DevOps Workflows

Security automation ensures that compliance and governance are consistently enforced. AWS Config provides continuous monitoring of resources and checks against compliance rules. GuardDuty analyzes logs for signs of malicious activity. Security Hub consolidates findings from multiple services into a single dashboard.

By integrating these services into DevOps workflows, you create a system that identifies and remediates security issues automatically. This reduces reliance on manual intervention and ensures a stronger security posture.

Cost Management and Optimization in AWS DevOps
