CodeBuild is a fully managed build service. It compiles your source code, runs tests, and produces deployable artifacts — scaling automatically so there are no build servers to manage.

The tell

When a scenario needs to compile code and run tests without maintaining build servers, that’s CodeBuild. It’s the build/test stage that CodePipeline usually invokes. Distinguish it from CodeDeploy (deployment) and CodeCommit (source repo).

Test yourself
