Reliability, Resilience, and Observability
Multi-AZ deployments, health checks, and circuit breakers convert single points of failure into gracefully degraded services. Rather than hoping outages never happen, you practice recovery so customers barely notice when components inevitably misbehave under load.
Reliability, Resilience, and Observability
A payments team scheduled game days to simulate dependency failures. The first run felt risky; later exercises became routine. Mean time to recovery dropped, and postmortems turned from blame into learning, because practice made resilience muscle memory, not myth.
