Chaos Engineering has consistently demonstrated its value in identifying failure modes and preventing outages, thus protecting companies from significant financial losses. However, as organizations attempt to scale Chaos Engineering beyond individual teams, they often encounter obstacles, such as limited expertise being concentrated within small groups, which hinders widespread implementation. To enhance an organization's reliability at scale, it is essential to integrate Chaos Engineering with a scalable approach that includes standardized tests, validation, and reporting. These practices should expand beyond critical systems to include all services, ensuring overall application resilience. Regular testing, facilitated by automation, and accountability through reporting and metrics are crucial for maintaining system reliability. Gremlin offers a platform designed to support this scaling process, providing tools like Reliability Management test suites and Dependency Discovery to help organizations uncover and address availability risks before they impact users.
