Resilience Testing

Verifying your system handles failure the way your runbook says it does.

Overview

What this engagement covers.

We inject controlled failures to verify that your circuit breakers, retries, and fallbacks behave as designed. Findings surface gaps between your runbook and actual system behaviour.

Failure injection design

Failure scenarios mapped to your architecture's known risk points.

Circuit breaker testing

Breaker open/half-open/close transitions verified under real load.

Retry and timeout validation

Retry storms, timeout cascades, and idempotency failures surfaced.

Failover testing

Active-passive failover timing measured and compared to RTO targets.

Disaster recovery verification

Full DR runbook executed and gaps documented.
