# Continuous delivery with CodePipeline
<a name="continuous-delivery-codepipeline"></a>

Continuous delivery is a release practice in which code changes are automatically built, tested, and prepared for release to production. With CloudFormation and CodePipeline, you can use continuous delivery to automatically build and test changes to your CloudFormation templates before promoting them to production stacks. This release process lets you rapidly and reliably make changes to your Amazon infrastructure.

For example, you can create a workflow that automatically builds a test stack when you submit an updated template to a code repository. After CloudFormation builds the test stack, you can test it and then decide whether to push the changes to a production stack. For more information about the benefits of continuous delivery, see [What is continuous delivery?](http://www.amazonaws.cn/devops/continuous-delivery/).

Use CodePipeline to build a continuous delivery workflow by building a pipeline for CloudFormation stacks. CodePipeline has built-in integration with CloudFormation, so you can specify CloudFormation-specific actions, such as creating, updating, or deleting a stack, within a pipeline. For more information about CodePipeline, see the [Amazon CodePipeline User Guide](https://docs.amazonaws.cn/codepipeline/latest/userguide/).
