There are Chaos Monkey, Simian Army, and other Netflix tools aimed at chaos engineering. What Netflix did with Chaos Monkey and the other tools is excellent. They were pioneers, at least among those that made their tools public. However, Chaos Monkey does not work well in Kubernetes. On top of that, it requires Spinnaker and MySQL. I don’t believe that everybody should adopt Spinnaker only for chaos engineering. Not working well in Kubernetes is a huge negative point and Spinnaker is another one. I’m not saying it’s a bad tool. Quite the contrary. Spinnaker is very useful for certain things. However, the question is whether you should adopt it only because you want to do some chaos engineering? Most likely not. If you are already using it, Chaos Monkey might be the right choice, but I cannot make that assumption.
