| Chaos engineering is a strategy for stress testing software in a complex, distributed computing environment. An important goal of chaos engineering is to proactively identify which components of an application stack could cause cascading failures downstream. Chaos engineering is a relatively new approach to software testing and software quality assurance (QA) and Netflix is a notable pioneer of the concept. The streaming media company was among the first to formalize the strategy and build tools the company's engineers could use to run controlled tests in live production environments. Today, engineers in many industry verticals work with Netflix's open sourced Simian Army tools to gradually inject live systems with specfic types of failure. First they define the system's normal behavior and then they deliberately introduce a disruption, such as rebooting a host container, to measure how it impacts overall system behavior.
