Operations
Design
Operations is about cycling through watch, notice, recover, and learn. We organize disaster recovery, backup, monitoring, incident response, request handling, and maintenance.
The 6 items in this chapter

Watch, notice, recover
Monitoring is the heart of operations. Visualize state, notice anomalies early, and recover by set procedures. After handling, reflect and improve.

Backup/Restore
Decide frequency, retention, and restore procedures, then test that you can actually restore.

Request handling and maintenance
Decide how to handle inquiries, work requests, and planned maintenance notices.
Monitoring and failures
- Decided monitoring items and thresholds.
- Decided incident response flow.
- Prepared disaster recovery procedures.
Data recovery
- Decided backup frequency.
- Actually tested restore.
- Verified alignment with RTO/RPO.
Daily operations
- Decided the request contact point.
- Check maintenance notices.
- Decided the retrospective method.
