Uber operates across the world with 1500+ APIs that powers our customer-facing applications. The API gateway provides a single unified platform for developing and launching new APIs seamlessly via a UI portal.

The first-generation of this gateway was a Node.js repository with 1000s of engineers making code changes each day to interact with 3000 internal microservices. In this talk, we will review the lessons learned from rebuilding this first-generation system into a fully self-served API Management Platform in GoLang.

We delve into complexities of schema enforcements, protocol conversions, security, auditing, localization, rate limiting, and lifecycle management.
