Testing
Network faults are the most common source of distributed system bugs, and also the hardest to test. A unit test can stub a database call. An integration test can verify a happy-path HTTP request. But what tests verify that your application handles a 5-second connection timeout gracefully? Or

When the Netflix Chaos Monkey paper was published, it proved a point: you can deliberately break production systems and come out stronger. But replicating that capability required deep engineering investment. Gremlin was built to package that capability as a commercial platform—safe, auditable, and accessible to teams that do not
Testing
A system that works under ideal conditions is not a reliable system—it is an untested one. Every production environment eventually experiences hardware failures, network partitions, resource exhaustion, dependency timeouts, and software bugs. Fault injection testing is the practice of deliberately introducing these conditions into a system to verify it
Testing
Netflix streams to over 230 million subscribers worldwide. When a server fails at 9 PM on a Friday, the engineers on call cannot afford to learn for the first time that their service cannot handle the outage. Chaos Monkey was born from this exact problem: a tool that randomly terminates
