Autonomous Chaos Engineering: Agents That Break Things (Safely)
When Netflix introduced Chaos Monkey over a decade ago, the premise was radically simple: randomly terminate instances in production to force engineers to build resilient systems. It was blunt, effective, and terrified everyone who wasn’t Netflix. Over time, chaos engineering matured. We moved from random destruction to controlled experiments. Tools like Gremlin, Chaos Mesh, and LitmusChaos allowed SREs to precisely target blast radiuses—injecting latency into a specific microservice or dropping packets between two zones. But even with these tools, chaos engineering remained a high-friction activity. It required an SRE to hypothesize a failure mode, write the experiment code, schedule a “game day,” run it manually, and analyse the results. ...
