During a city payroll outage, operators argue about whether the fault is the application or an AWS Regional service event. What should HA runbooks emphasize?
Select an answer to reveal the explanation.
Short Explanation
Before rewriting the payroll app, peek at the weather map—AWS Health tells you if the platform itself is storming. Separating Regional events from app bugs saves hours of wrong fixes. Turning alarms off just flies blind.
Full Explanation
High-availability operations depend on visibility into platform health as well as application metrics. AWS Health Dashboard and related service health signals help operators decide whether an incident is a Regional AWS event or an application defect. Runbooks should check those signals early. Assuming every failure is application-only, delaying health review until after rebuilds, or disabling alarms removes critical decision inputs during HA events.
