What is Chaos Engineering?
Deliberately injecting failures into a system to test its resilience. Netflix's Chaos Monkey randomly kills servers to ensure the system survives.
Chaos Engineering is a advanced concept that sits in the Reliability & Resilience area of system design. Engineers reach for it whenever they need to reason about real-world trade-offs in that space — not just for textbook correctness, but because real production systems at companies like Netflix, Amazon, and Google make these decisions every day.
If you want to go deeper than this definition — with diagrams, code, and a quiz to lock it in — work through the "Chaos Engineering" lesson linked below. It walks through the why, the mechanism, the trade-offs, and how the giants actually use it in production.

Circuit Breaker
A pattern that stops calling a failing service after repeated failures, preventing cascade failures. Like an electrical circuit breaker that cuts power to prevent fires.
Bulkhead
A pattern that isolates different parts of a system so a failure in one part doesn't sink the whole ship. Named after the compartments in a ship's hull.
Retry
Automatically re-attempting a failed operation, usually with exponential backoff. Essential for handling transient failures in distributed systems.
