My point is that nomatter how well engineered your system is, to actually have chaos monkey running in production really depends on the risk profile and scale of your business.

As soon as chaos monkey cause a service interrupt for, say, traders - it would get turned off and whoever had such a bright idea fired. But if it causes a service interruption for a tiny proportion of people watching streaming videos - no big deal.

Its proponents just ignore this practical reality and seem politically unaware.
