Resilience Case Study: Chaos Engineering.
Chaos Engineering started in the mid 2000s. It was made famous by the Netflix engineering team under an internal app they developed, called Chaos Monkey, that randomly destroyed pieces of their customer-facing infrastructure, on purpose, so that their network architects could understand resilience engineering down deep in their core. But the concept is much more than simply destroying production systems to see what will happen. This elevates the idea of regression testing to the level of the scientific method designed to uncover potential and unknown architectural designs that may cause catastrophic failure. I make the case that the CSO should probably own that functionality.
