What is blast radius in chaos engineering?

Blast radius = percentage of users or requests impacted by a failure injection. High blast radius = risky experiment. Start with experiments affecting <1% of traffic (canary), then expand as confidence builds.

How do I limit blast radius for chaos experiments?

Use feature flags to target specific user segments, start in staging not production, use traffic percentage controls (1% -> 10% -> 50%), and have automated rollback triggers.

What is a good first chaos engineering experiment?

Terminate a single non-critical EC2 instance and verify auto-scaling replaces it. Or kill one pod in a redundant k8s deployment. Verify auto-recovery before harder experiments.
