AWS DevOps Advanced

Master advanced AWS DevOps concepts including enterprise CI/CD architectures, GitOps, ECS/EKS deployments, Infrastructure as Code, Blue-Green deployments, Canary releases, DevSecOps, Observability, Multi-Account CI/CD, and production best practices.

Introduction

Modern enterprises deploy software hundreds or even thousands of times every day. AWS DevOps provides a complete ecosystem for automating builds, deployments, infrastructure provisioning, monitoring, security, and disaster recovery.

Large organizations such as Amazon, Netflix, Capital One, Adobe, Expedia, and Airbnb leverage AWS services to build highly available, scalable, secure, and fully automated deployment pipelines.

This guide explores advanced AWS DevOps concepts used in production environments and frequently discussed in senior-level interviews.

Traffic switches after validation.

Advantages

  • Zero Downtime
  • Instant Rollback

Canary Deployment

Suitable for stateless services.


Artifact Management

Artifacts include

  • JAR
  • WAR
  • Docker Images
  • Lambda Packages
  • Helm Charts

Repositories

  • CodeArtifact
  • Amazon ECR
  • S3

Never rebuild production artifacts.


DevSecOps Pipeline

  • SonarQube
  • Snyk
  • Checkov

Secrets Management

Never store secrets inside repositories.

AWS Services

  • AWS Secrets Manager
  • Systems Manager Parameter Store
  • IAM Roles
  • KMS

Monitoring & Observability

Production systems should monitor

  • CPU
  • Memory
  • Response Time
  • Error Rate
  • Availability
  • Deployment Status

Real-World Example

A developer pushes a Spring Boot microservice to GitHub.

  1. GitHub triggers AWS CodePipeline.
  2. CodeBuild compiles the application.
  3. Unit tests execute automatically.
  4. SonarQube performs static code analysis.
  5. Trivy scans dependencies and the Docker image.
  6. Docker image is pushed to Amazon ECR.
  7. ArgoCD detects the Kubernetes manifest update.
  8. Amazon EKS performs a Canary deployment.
  9. CloudWatch and AWS X-Ray monitor the deployment.
  10. If error rates exceed the defined threshold, CodeDeploy automatically rolls back to the previous stable version.
  11. Amazon SNS sends deployment status notifications to the engineering and operations teams.
