chaos-engineering

To design a safe chaos engineering experiment, define a clear hypothesis, identify measurable steady-state metrics, select a targeted fault injection type, and set explicit abort criteria with rollback plans to keep Kubernetes service risk bounded.

Blast radius calculation estimates expected impact before fault injection. You need blast radius planning to bound risk, preventing controlled resilience tests from escalating into production customer incidents across AWS or Kubernetes environments.

Write a blameless postmortem by documenting experiment outcomes, surprises, and follow-up actions. Structured postmortems turn Game Day and resilience testing results into learning documents without assigning blame for fault injection behavior.

Yes, you can use this chaos engineering approach to test AWS dependency failover behavior. It supports planning latency injections, dependency failures, and validating failover mechanisms by applying hypothesis writing and steady-state measurement across service dependencies.

For a resilience experiment, you need steady-state metrics representing normal system behavior and abort criteria defining when to halt testing. These components measure deviations and trigger rollback plans if fault injection causes unexpected degradation.
