Injecting Chaos

Killing instances

The next step is to apply knowledge of the system to inject chaos. We know the structure of the system well enough to guess where we can kill an instance, add some latency, or make a service call fail. These are all injections. Chaos Monkey does one kind of injection: it kills instances. Killing instances is the most basic and crude kind of injection. It will absolutely find weaknesses in the system, but it’s not the end of the story.
