GitHub Actions CI/CD pipeline with AWS ECS blue/green deployment automates code testing, Docker image builds, and zero-downtime production releases. Developer commits trigger GitHub Actions to checkout code, build and push Docker images to ECR, run unit/integration/security tests, and conditionally deploy across Dev, Staging, and Production ECS clusters. Blue/green deployment on Production enables traffic shifting between active and new task versions with automated health checks and instant rollback capability. This architecture demonstrates GitOps best practices for safe, repeatable deployments with CloudWatch monitoring and IAM role-based access control.
