Explore version promotion

At NovaTech, your team promotes artifacts across environments without rebuilding. Use the version promotion flow to visualize how artifacts move from dev to staging to production without rebuilding.

The visualizer shows Lambda aliases, ECR tags, and API Gateway stages side by side. Click "Promote" to move a version between environments and see that the artifact stays the same — only the pointer (alias, tag, or stage) changes.

Question: Your team promotes a Lambda function from dev to prod by updating the "prod" alias. A bug is discovered. What is the fastest way to roll back?
