From Notebook to Production

A notebook proves an idea. A service survives real traffic. Bridging the two is mostly discipline.

The checklist

• Pin your dependencies — reproducibility first.
• Add a health check — know when it's down before your users do.
• Log inputs and outputs — you can't fix what you can't see.
• Set a timeout and a fallback — models fail; plan for it.
• Measure latency and cost — both are features.

Ship in slices

Deploy behind a flag, send 1% of traffic, watch the dashboards, then widen. Big-bang launches hide big-bang failures.

Production is not a place you arrive at once — it's a standard you keep.
