Choose hotfix, rollback, or feature disablement during an App Service incident

Reason through mitigation choices during a live App Service production incident.

Choose rollback, roll-forward, or kill switch during incidents

Compares rollback, roll-forward, feature kill switches, scaling, and degraded mode as incident mitigations.

Choose rolling, blue-green, or canary deployment

Chooses a deployment strategy from capacity, compatibility, risk, observability, and rollback needs, then defines progressive promotion and abort signals.
