Capabilities in This Epic
Chaos Engineering Practices
>= 60% of critical services undergo monthly chaos experiments (pod failures, network latency, resource exhaustion).
Automated Disaster Recovery
>= 80% of critical services have automated DR failover tested quarterly with RTO < 1hr and RPO < 15min.
Circuit Breaker Patterns
>= 75% of service-to-service calls protected by circuit breakers (Istio, Envoy, Resilience4j) preventing cascade failures.
Adaptive Rate Limiting
>= 80% of public APIs have adaptive rate limiting protecting against traffic spikes and abuse.
Graceful Degradation Strategies
>= 70% of services implement degraded mode (serve cached data, disable non-critical features) during dependency failures.

Mitigation: Start with non-prod environments. Use GameDays with planned windows. Have rollback ready. Communicate experiments.
Mitigation: Tune thresholds based on actual traffic patterns. Implement exponential backoff. Monitor false positive rate.
Mitigation: Test runbooks in chaos experiments. Update runbooks after each incident. Version runbooks with infrastructure.
