Chaos Engineering is a practice used in software development to improve system resilience by intentionally introducing failures into a controlled environment. The goal is to identify weaknesses and understand how systems respond under stress, allowing teams to build more robust applications. By simulating unexpected disruptions, such as server outages or network issues, organizations can observe how their systems behave and recover. This proactive approach helps teams to enhance their incident response strategies and ensures that services remain reliable, even during unforeseen challenges.
