Production Readiness

Monitoring and Observability

Application Monitoring

• Performance: response time | throughput | latency percentiles (P50, P95, P99)
• Resources: CPU | memory | database connections | cache hit rates
• Errors: exception tracking | error rate trends | integration failure detection
• Business: KPI tracking | conversion funnels | feature usage | revenue impact

Infrastructure Monitoring

Server/container health and resource utilization | Network performance and connectivity | Storage capacity and I/O performance | Security event detection.

Alerting Tiers

Tier	Condition	Response
Page	Service down, data loss risk, security breach	Immediate response
Urgent	Error rate >2x baseline, latency SLA breach	Response within 15 min
Warning	Capacity >80%, error rate trending up	Response within 1 hour
Info	Deployment complete, metric threshold crossed	Review next business day

Operational Procedures

Incident Response

1. Detect: automated alerting identifies issue
2. Triage: classify severity, assign responder
3. Communicate: notify stakeholders per severity level
4. Resolve: apply fix or rollback
5. Review: post-incident review within 48 hours
6. Improve: update runbooks and monitoring based on findings

Maintenance Procedures

Regular update and patching schedule | Backup verification (test restores quarterly) | Security vulnerability scanning (automated, weekly) | Performance baseline recalibration (after major changes).

Knowledge Transfer

Operational runbooks for common procedures | Architecture documentation with system diagrams | Deployment procedures and configuration management | Troubleshooting guides for known failure modes.

Quality Gates for Production Readiness

Before declaring production-ready, all must pass:

• All acceptance tests passing
• Unit coverage meets project standard (default: >= 80%)
• Integration tests validated
• Performance validated under realistic load
• Security scan completed (0 critical, 0 high)
• Monitoring and alerting configured
• Logging structured and searchable
• Rollback procedure documented and tested
• Runbook created for operational procedures
• On-call team trained on new feature
