Implementation plan:
- Log retention policies: balancing cost and compliance
- Structured logging: why JSON logs are better than plain text for searching
- Basic incident triage workflow: alert fires → check dashboard → check logs → identify root cause
- Common issues and where to look: 5xx errors (app logs), high latency (ALB metrics), OOM (ECS metrics)
- Practice: guided troubleshooting exercise — given a broken deployment, use CloudWatch logs, metrics, and alarms to find the root cause
