AWS CodeBuild
- What it is
- Fully managed build service: compiles source, runs tests, and produces deployable artifacts.
- Serverless — no build servers to provision, patch, or scale. Builds run in parallel automatically.
- How it works
- A
buildspec.ymlfile in the repository defines the build phases and commands. - Billed per build minute by compute size, so there is no idle build-fleet cost.
- A
- Where it sits in the pipeline
- Build/test stage between AWS CodeCommit (source) and AWS CodeDeploy (deploy), orchestrated by AWS CodePipeline.
- Contrast with
- Running Jenkins on Amazon EC2 — you own patching, scaling, and the cost of idle capacity.
