Despite the fact that the word "chaos" generally denotes an undesirable state of being, for DevOps teams the practice of chaos engineering can lead to very positive results. For the past five years, San Jose, Calif.-based Gremlin has been in the business of helping organizations employ chaos engineering techniques. With chaos engineering, faults and error conditions are intentionally injected into running processes and platforms to see how they and the teams that support them react.
