Flipr: Uber’s Dynamic Configuration Platform

Uber’s many software systems require a high volume of changes every day. Because of our systems’ size and complexity, it is a significant challenge to implement these changes without unintended consequences, and without slowing down developer productivity. Flipr is a big part of Uber’s solution to solving this problem. Flipr is a tool that we created for dynamic configuration management, such as feature flags, allowlists, incremental rollout, and other advanced use cases. In this talk, we will describe what Flipr is, how it’s used, and how it’s now become the foundational piece of a self-service configuration platform.
