CodePipeline Basics

• It is a continuous integration and continuous delivery service
• It is used for fast and reliable application and infrastructure updates.
• It builds, tests, and deploys code every time there is a code change, based on the release process models you define.
• It automates the steps required to release software changes continuously.

Example release process using CodePipeline

In this example,

• When developers commit changes to a source repository, CodePipeline automatically detects the changes.
• Those changes are built, and if any tests are configured, those tests are run.
• After the tests are complete, the built code is deployed to staging servers for testing.
• From the staging server, CodePipeline runs additional tests, such as integration or load tests.
• Upon the successful completion of those tests, and after a manual approval action that was added to the pipeline is approved
• CodePipeline deploys the tested and approved code to production instances.
