In few hours, quickly learn how to effectively leverage various AWS services to improve developer productivity and reduce the overall time to market for new product capabilities. In this session, we demonstrate a prescriptive approach to incrementally adopt and embrace some of the best practices around continuous integration and delivery using AWS developer tools and third-party solutions, including AWS CodeCommit, AWS CodeBuild, Jenkins, AWS CodePipeline, AWS CodeDeploy, AWS X-Ray, and AWS Cloud9. We also highlight some best practices and productivity tips that can help make your software release process fast, automated, and reliable.
