What is Chaos Engineering?

The discipline of deliberately introducing failures into a system to test its resilience and identify weaknesses before they cause outages.

Chaos engineering, pioneered by Netflix with Chaos Monkey, proactively tests system resilience. Experiments include killing servers, injecting network latency, filling disks, and simulating region failures. The goal is finding weaknesses before they cause real outages.

Principles include defining steady state, hypothesizing what will happen, running experiments in production, and minimizing blast radius. Tools include Chaos Monkey, Gremlin, and Litmus. Start small and gradually increase experiment scope.
