What makes a backend ready for production?
Try code in the playgroundUnderstand the concept
Production readiness means an application can be operated, monitored and recovered under normal load and failure. Working business logic is only one part; configuration, resource limits, startup, shutdown and observability also affect users. A ready service should fail clearly and avoid accepting work it cannot safely complete.
Important ideas
-
Validate config at startup; store secrets outside source code.
-
Add structured logs, request IDs, readiness checks and bounded connection pools.
-
On shutdown, stop new work, finish active work within a timeout and close resources.
-
Liveness asks whether restarting may help; readiness asks whether this instance should receive new traffic.

Turn this concept into a clear answer.
- Describe graceful shutdown as stop accepting → drain active work → close resources → exit within a deadline.
