AWS CodeDeploy
AWS CodeDeploy automates application deployments to supported compute targets with configurable rollout behavior. It can shift traffic between GenAI API versions while alarms and hooks validate operational health.
Key points
- Deployment groups define targets and rollout configuration
- Blue/green and in-place options depend on compute platform
- Lifecycle hooks can run validation before or after traffic changes
When to use it
- Canary a new Lambda-based model adapter
- Blue/green deploy an ECS inference gateway
Exam tips
- Use CodeDeploy for application rollout mechanics; model quality gates still belong before and during promotion
- Tie rollback alarms to safety, quality, errors, and latency rather than health checks alone
