The one thing that is appealing to an "AWS shop" and something that GitHub and other services have a harder time emulating is the integration with IAM (user authentication and provisioning) and the CloudTrail (audit trails). For any reasonably sized organization, ensuring that users get provisioned / deprovisioned is a tricky, error-prone task. Having IAM as a single toggle is nice. Using their SAML integration into something like Okta, OneLogin, or other IaaS-providers ... even better. Getting user activity into centralized logging via CloudTrail (Splunk, Sumo, ELK, et al.) is best practice for security teams. AWS makes all of this pretty easy, but at a price.

That's not just it. They are planning to add post-receive hooks. Imagine doing a commit and writing a post-commit hook to auto-deploy to appropriate hosts or spawn up an EC2 instance to run integration tests.
