Definitions

1. A tool created by Netflix that randomly terminates production instances to ensure that engineers build resilient services that can tolerate unexpected failures. Part of the broader Simian Army toolkit. Pioneered the chaos engineering discipline and inspired similar tools across the industry.

   In plain English: Netflix's tool that randomly breaks things in production on purpose, to make sure the system can handle failures.

   Example: "Chaos Monkey killed three instances during peak traffic and nobody noticed — that's how you know your redundancy works."
