We start Module 4 on DevOps and Observability for AI-Built Apps.

Once your application is deployed, you need to know what it is doing. With observability, you can see where the app failed, investigate with the right context, and decide how to respond.

We cover:

- What to observe in a running application
- Which failures should trigger alerts
- What context an investigation needs
- Where coding agents can help with operations safely
- Which production permissions stay with humans
