What is AWS CodePipeline?

AWS CodePipeline is a continuous integration and continuous delivery (CI/CD) service that automates the build, test, and deploy phases of your release process. It enables you to model your release workflow from source code to production deployment. CodePipeline integrates with services like CodeCommit, GitHub, CodeBuild, CodeDeploy, and third-party tools. It provides visual workflow management and supports parallel execution of actions. Each stage can have multiple action groups, and the service automatically triggers pipeline execution when source code changes. CodePipeline includes manual approval actions for governance and integrates with CloudWatch Events for notifications and Lambda for custom actions.
