Infrastructure Review

When to Use

When reviewing deployment configs, CI/CD pipelines, monitoring setup, scaling strategies, or incident response.

Checklist

Deployment

• Health checks configured
• Graceful shutdown handling
• Rolling deployment (zero downtime)
• Rollback procedure documented
• Resource limits set (CPU, memory)

Monitoring & Alerting

• Application metrics exported (latency, errors, throughput)
• Alerts on error rate spike and latency P99
• Log aggregation configured
• Uptime monitoring on critical endpoints

Reliability

• Retry logic with exponential backoff
• Circuit breakers on external dependencies
• Timeouts on all network calls
• Graceful degradation when dependencies fail

CI/CD

• Tests run before deploy
• Linting and type checking in pipeline
• Secrets injected from CI, not committed
• Deploy requires approval for production

Incident Response Template

1. Detect — what alert fired?
2. Assess — impact scope (users, data, revenue)
3. Mitigate — rollback, feature flag, or hotfix
4. Resolve — root cause fix
5. Review — blameless postmortem within 48h
