My last company I worked at, they had like 30% of the staging environment running production stuff. They also had only one deploy target, which is drum roll production, which meant all of staging AND some of Dev/QA was live and could interact with the production environment. Also fun to see the production load at 300% of expected, burning, only to find out some event, data roll up, query, whatever was being run in duplicate on 10 different machines because somebody forget to to manually edit the configs after they rolled out a new version to staging/QA. Although I think this would qualify as "chaos engineering", I don't think it fits with what netflix is going for. Yeah, ok that had nothing to do with the OP, sorry, I just had to vent.
