Which service can model, visualize, and automate the steps required to release your software?

• A. AWS CodeStar
• B. AWS CodeDeploy
• C. AWS CodePipeline
• D. AWS Cloud9

Answer: (C)

Automating and visualizing a software release workflow is what CodePipeline is built for. It lets you model the release process as a pipeline with stages (such as Source, Build, Test, Deploy) and actions at each stage, giving a clear visual view of how artifacts flow from code to production. This pipeline can be triggered automatically when changes occur, and you can include gates or approvals to control the release.

CodePipeline integrates with other AWS developer tools (CodeCommit, CodeBuild, CodeDeploy) and third-party tools, so you can automate the entire end-to-end release—from building and testing to deploying to environments—without manual steps. It’s specifically designed to orchestrate and visualize the progression of your software release, making it the best fit for this capability.

The other services serve related but narrower roles: CodeStar provides a project-oriented dashboard and templates, CodeDeploy handles deployment to targets, CodeBuild focuses on building artifacts, and Cloud9 is an integrated development environment.
