Chaos Engineering
A GameDay is a structured chaos engineering exercise where a team deliberately introduces failures into a system and practices responding. Unlike automated chaos experiments that run continuously, GameDays involve the whole team — operations, development, and sometimes management — in a real-time scenario. Amazon, Netflix, and Google run them regularly. Here&
Resilience Testing
Resilience testing is the practice of verifying that your system handles failures gracefully. This covers more than chaos engineering — it includes unit-level tests for circuit breakers and retry logic, integration tests that simulate dependency failures, and chaos experiments that inject real failures into running systems. This guide covers the
Chaos Engineering
Chaos Monkey is the tool that started chaos engineering. Netflix built it in 2011 to randomly terminate EC2 instances during business hours — forcing engineers to build systems that assumed any server could disappear at any time. The open-source version runs on AWS and Spinnaker. For Kubernetes, Chaos Mesh or
Chaos Engineering
Chaos engineering is the practice of deliberately introducing failures into a system to find weaknesses before they cause incidents. The core idea: if you run controlled experiments that break things on purpose, you discover fragility in a controlled way rather than during a real outage. Netflix popularized it with Chaos
