What is Chaos Engineering?
⚡
Quick Answer
Chaos Engineering is the practice of deliberately injecting controlled failures (killing instances, adding latency, partitioning networks) to test and improve a system resilience before real incidents expose weaknesses.
Detailed Answer
You form a hypothesis about steady-state behavior, inject a fault in a controlled blast radius (ideally in production with guardrails), and verify the system copes — or learn where it does not. Tools like Chaos Mesh, Gremlin, and the original Chaos Monkey automate this. It validates redundancy, failover, and alerting for real.

Interview Tip
Stress hypothesis-driven experiments with a limited blast radius — chaos is disciplined, not random breakage.
