A pipeline defines your release process workflow, and describes how a new code change progresses through your release process. A pipeline comprises a series of stages (e.g., build, test, and deploy), which act as logical divisions in your workflow. Each stage is made up of a sequence of actions, which are tasks such as building code or deploying to test environments. AWS CodePipeline provides you with a graphical user interface to create, configure, and manage your pipeline and its various stages and actions, allowing you to easily visualize and model your release process workflow.

Parallel Execution
You can use CodePipeline to model your build, test, and deployment actions to run in parallel in order to increase your workflow speeds.

AWS CodePipeline can pull source code for your pipeline directly from AWS CodeCommit or Amazon S3. It can run builds and unit tests in AWS CodeBuild. CodePipeline can deploy your changes using AWS CodeDeploy, AWS Elastic Beanstalk, Amazon Elastic Container Service, or AWS OpsWorks.

You can model AWS CloudFormation actions that let you provision, update, or delete AWS resources as part of your release process. This also enables you to continuously deliver serverless applications built using AWS Lambda, Amazon API Gateway, and Amazon DynamoDB with the AWS Serverless Application Model.

You can also trigger custom functions defined by code at any stage of your pipeline using CodePipeline's integration with AWS Lambda. For example, you can trigger a Lambda function that tests whether your web application deployed successfully.

CodePipeline lets you configure a pipeline that ties these services together along with third-party developer tools and custom systems.

AWS CodePipeline allows you to integrate third-party developer tools, like GitHub or Jenkins, into any stage of your release process with one click. You can use third-party tools for source control, build, test, or deployment. Learn more about our integrations here.

AWS CodePipeline allows you to integrate your own custom systems. You can register a custom action that allows you to hook your servers into your pipeline by integrating the CodePipeline open source agent with your servers. You can also use the CodePipeline Jenkins plugin to easily register your existing build servers as a custom action.

AWS CodePipeline allows you to define your pipeline structure through a declarative JSON document that specifies your release workflow and its stages and actions. These documents enable you to update existing pipelines as well as provide starting templates for creating new pipelines.

AWS CodePipeline uses AWS IAM to manage who can make changes to your release workflow, as well as who can control it. You can grant users access through IAM users, IAM roles, and SAML-integrated directories.
