Chaos Engineering: Proactively Discovering System Weaknesses
Overview The traditional approach to reliability is “try not to have failures” — add monitoring, add alerts, add redundancy. But this passive defense has a fundamental flaw: you don’t know how the system actually behaves during a failure until one actually occurs. Chaos engineering takes the opposite approach: proactively and controllably inject failures to discover system weaknesses before they become incidents. It’s not about causing destruction — it’s a scientific experimental method: form a hypothesis (“the system should be able to withstand a node failure”), design an experiment (kill a node), verify the hypothesis (is the service still working?...
