People have been doing Chaos Engineering, and the more general category of "DevOps", for years before those things were given labels. I think we may credit Netflix with the awesome name of Chaos Monkey and for building a systemic in-house practice, but they were not the first to perform intentional destructive resilience testing in production. Case in point, I've been yanking out active drives, cables, PSUs and CPUs since the 1980s, and not always by accident. What's more, I was taught to do by someone who'd been babysitting VAXes for years; they had a ceramic axe that, at the age of fourteen, I'd seen them swing right through a three-phase minicomputer power feed at my local university's data center "for test purposes".
