Watch closely #

  • timeout alignment across proxy, uWSGI, and app
  • worker count versus DB pool size
  • memory growth per worker
  • background work running inside web processes
  • request-level logging and correlation IDs

Reminder #

Flask stays simple in production only when process model and operational boundaries are explicit.
