The Production Readiness Checklist: 10 Critical Checks Before You Ship to Prod Shipping code is easy; keeping systems resilient, observable, and secure under real-world load is the real challenge. Run through this production readiness checklist before every major release to prevent preventable outages: 1. Reliability & Resilience [ ] Graceful Shutdowns: Containers handle SIGTERM signals properly, completing in-flight requests before terminating. [ ] Health Checks Configured: Separate liveness and readiness probes are defined and accurately reflect internal state. [ ] Circuit Breakers & Timeouts: All external API calls, database queries, and third-party integrations enforce strict timeouts and fallback mechanisms. 2. Observability & Monitoring [ ] Structured Logging: Logs output in JSON format with standardized context (timestamp, trace_id, user context, severity). [ ] Alerting Thresholds Set: PagerDuty/Opsgenie alerts trigger only on actionable, high-severity SLO breaches—not transient warning spikes. [ ] Distributed Tracing: Request headers propagate correlation IDs across microservice boundaries. 3. Security & Governance [ ] Zero Hardcoded Secrets: Environment variables and KMS manage all API keys, certificates, and database credentials. [ ] Least Privilege Access: Services run under restricted IAM roles and dedicated non-root users. [ ] Dependency Audits: Vulnerability scanners (Snyk, Trivy, Dependabot) pass with zero critical/high CVEs. 4. Performance & Scalability [ ] Database Indexes Verified: Queries touched by new endpoints are profiled and backed by appropriate indexes. [ ] Rate Limiting Active: Critical endpoints enforce token-bucket or sliding-window rate limits to deter abusive traffic. Key Takeaways Standardize Pre-Flight Checks: Checklists turn tribal engineering knowledge into repeatable operational rigor. Observe Before You Scale: If you cannot trace a failed request in under 60 seconds, you are not ready for production traffic. Fail Gracefully: Timeouts and circuit breakers prevent localized glitches from cascading into complete system failures. CTA Tired of debugging production fire drills alone?
