What Is Chaos Engineering?
Chaos engineering deliberately introduces failures into production systems to test resilience. By breaking things on purpose in a controlled way, teams discover weaknesses before they cause real outages.
How Chaos Engineering Works
Netflix pioneered chaos engineering with Chaos Monkey, which randomly kills production instances. The philosophy: if your system can't handle a server dying, it's not resilient enough. Tools: Chaos Monkey, Gremlin, LitmusChaos. Start with staging before moving to production experiments.
Key Concepts
- Chaos Monkey — Netflix's tool that randomly terminates production instances to test auto-recovery and redundancy
- Game Days — Scheduled chaos experiments where teams deliberately inject failures and practice incident response
Frequently Asked Questions
Is chaos engineering safe for production?
Yes, when done carefully. Start with known failure modes, have rollback plans, limit blast radius, and monitor closely. The whole point is finding problems before customers do.
