Go in Production: patterns that survive fintech

Go in Production: patterns that survive fintech

Short summary

Production Go in fintech demands battle-tested patterns: graceful shutdown with 25-second SIGTERM handling, ordered middleware chains (metrics → logging → recovery → auth), and circuit breakers for flaky services. Implementation details cover lifecycle management with errgroup, panic recovery in handlers, structured logging with request IDs for traceability, and GDPR compliance. Boring, well-tested code outlasts clever code in financial production.

  • •Graceful SIGTERM shutdown within 25 seconds prevents data loss during deployments
  • •Strict middleware order (metrics → logging → recovery → auth) ensures reliability
  • •Circuit breakers, structured request IDs, and GDPR compliance prevent cascading failures
