What is this?
Chaos Monkey is a resiliency tool from Netflix that randomly terminates virtual machine instances and containers in your production environment, so engineers face failures often enough that they build services able to tolerate them.

The tool follows the Principles of Chaos Engineering: injecting real failures regularly so weaknesses show up before a real outage finds them.

It is written in Go, so it ships as a single binary.

So far it has been tested with AWS, GCE and Kubernetes.

Randomly terminating instances turns outages into routine events that engineers design for, instead of rare emergencies they discover at 3am.
