At Amazon, continuous integration and continuous delivery (CI/CD) techniques enable collaboration, increase agility, and deliver a high-quality product faster. In this talk, we walk you through the practices we use for both the CI and the CD of software delivery. For CI, we showcase how we incorporate pull requests to increase team collaboration. We also demonstrate how to optimize CI workflows for speed with caching, code analysis, and integration testing. For CD, we share example safety mechanisms, including canary testing, rollbacks, and Availability Zone redundancy. We use the AWS developer tools that were designed based on the internal Amazon tooling: AWS CodeCommit, AWS CodeBuild, AWS CodePipeline, AWS CodeDeploy, and AWS X-Ray.
