The first thing that happens in production is silence. A tool call fails, and you have no idea why. There are no logs, no way to know if the server is healthy or degraded. One misbehaving client sends 500 requests per second and every other client suffers. You push a new version and in-flight requests get killed mid-execution.

The gap between a demo server and a production server is not about features. It is about the infrastructure that keeps things observable, resilient, and safe when real traffic hits.

This lesson covers the patterns that bridge that gap, with working Python code you can adapt to your own servers.
