Failure Flags, a tool designed to enhance application-level reliability through resilience testing, has transitioned out of its Beta phase and is now generally available. Over the past year and a half, it has been utilized by customers to conduct numerous tests on applications running on platforms such as AWS Lambda, Kubernetes, and Istio Service Mesh, using components like the Gremlin SaaS API and SDKs integrated into application code. The tool allows users to simulate application errors, latency, and data issues, helping teams manage common challenges like incorrect data and API changes. With SDKs available for popular languages such as Node.js, Python, Java, Go, and now .NET, Failure Flags enables creating experiments through a user-friendly Gremlin UI. This updated interface allows for easy configuration of tests, helping to standardize and scale resilience efforts across organizations. As part of Gremlin's automated reliability platform, Failure Flags aims to identify and mitigate availability risks before they affect users, with further improvements and optimizations already underway.
