The Discipline of Chaos Engineering
To put it simply, Chaos Engineering is one particular approach to “breaking things on purpose” that aims at teaching us something new about systems by performing experiments on them. Ultimately, our goal is to identify hidden problems that could arise in production. Only then will we be able to address systemic weaknesses and make our systems fault-tolerant. Chaos Engineering goes beyond traditional (failure) testing in that it’s not only about verifying assumptions. It also helps us explore the many unpredictable things that could happen and discover new properties of our inherently chaotic systems.
