Incident Response
Incident response is a structured process for handling production failures: detect→triage→mitigate→root-cause→fix→review.
Purpose
Handle failures fast and effectively, reducing downtime and impact.
Mechanism
Phases: 1) detect via alerts; 2) assign the on-call engineer; 3) mitigate (rollback/scale/rate-limit); 4) root cause investigation; 5) fix; 6) blameless postmortem. On-call rotations (PagerDuty).
Use cases
- Incident handling
- On-call management
- Postmortem-driven improvement
