👉 Chaos engineering is a proactive approach to improving system resilience and reliability by intentionally introducing controlled failures or disruptions into a system to test its ability to handle unexpected issues. This practice, pioneered by Netflix, involves deliberately simulating errors like network outages, server crashes, or data corruption to uncover vulnerabilities and ensure the system can gracefully degrade or recover. By exposing weaknesses before they impact real users, chaos engineering helps teams build more robust architectures, refine incident response strategies, and foster a culture of resilience—ultimately making systems more fault-tolerant in the face of real-world unpredictability.
