Explanation
A single multi-stage CodePipeline keeps the artifact consistent and allows manual approvals between environments.

Explanation
CodeDeploy canary for Lambda shifts traffic gradually and rolls back automatically when the alarm fires.
A team needs fast feedback on unit tests and slower integration tests without delaying deploys. Best pattern?
