# Chaos Studio Experiment

An Azure Chaos Studio Experiment defines a controlled set of fault injections used to test the resilience of your applications and infrastructure. It lets you orchestrate faults, target specific resources, and observe system behavior under stress. Experiments help identify weaknesses, validate recovery strategies, and improve overall reliability in a safe, repeatable way.
