AWS CodePipeline and CodeBuild#

AWS CodePipeline orchestrates CI/CD workflows as a series of stages. CodeBuild executes the actual build and test commands. Together they provide a fully managed pipeline that integrates natively with S3, ECR, ECS, EKS, Lambda, and CloudFormation. No servers to manage, no agents to maintain – but the trade-off is less flexibility than self-hosted systems and tighter coupling to the AWS ecosystem.

Pipeline Structure#

A CodePipeline has stages, and each stage has actions. Actions can run in parallel or sequentially within a stage. The most common pattern is Source -> Build -> Deploy:
