CodeBuild

Amazon CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages that are ready to deploy. With CodeBuild, you don’t need to provision, manage, and scale your own build servers.

CodeBuild scales continuously and processes multiple builds concurrently, so your builds are not left waiting in a queue. Because CodeBuild runs in AWS, it can leverage IAM Instance Profiles to assume roles to securely provision resources without exposing AWS access credentials.
