Kubernates를 위한 Chaos Engineering in Action :: 윤석찬 (AWS 테크에반젤리스트)
Chaos engineering involves intentionally introducing failures into systems to test resilience. It reveals issues that may otherwise remain undetected. Some key aspects of chaos engineering include using tools like Chaos Toolkit and Gremlin to fail components, running experiments at specified times using a configuration file, and introducing faults into service meshes between microservices. The goal is to build confidence in systems by identifying weaknesses before real failures occur.
