Optimizing Continuous Deployment at Uber: Automating Microservices in Large Monorepos
Briefly

Uber's redesign of its continuous deployment system, Up CD, significantly improves automation, safety, and transparency, streamlining the process for large scale microservices deployment.
In 2022, Uber acknowledged the inefficiencies in its deployment process and initiated a project to create a unified continuous deployment system for thousands of microservices.
Prior to the redesign, only 7% of Uber's 4,500 microservices were automatically deployed, resulting in frequent manual interventions and highlighting the need for a standardized deployment approach.
The Up CD system enables a more strategic deployment by focusing only on services affected by specific commits, thereby reducing unnecessary deployments and enhancing operational efficiency.
