How We Unified Configuration Distribution Across Systems at Uber

摘要

Uber has multiple, domain-specific products to manage and distribute configuration changes at runtime across our many systems. These configuration products cater to different use cases: some have a web UI that can be used by non-engineers to change product configuration for different cities, and others expose a Git-based interface that primarily caters to engineers.

While these domain-specific configuration products have different applications, they share common parts that can be consolidated for simplicity and to reduce the overhead of operations, maintenance, and compliance. This article will cover how we consolidated and streamlined our underlying configuration and rollout mechanisms, including some of the interesting challenges we solved along the way, and the efficiencies we achieved by doing so.
