In 2024, the Uber stateless container orchestration platform completed a migration from Apache Mesos® to Kubernetes®. This blog is the first in a multi-part series about Kubernetes migration use cases. Uber is gradually converging to Kubernetes for batch, stateless, and storage use cases. The goal is to leverage industry-standard technology, rich built-in functionality, and stability. This blog describes how we migrated all shared stateless workloads to Kubernetes. It describes our migration journey, including the motivation behind the migration, the challenges we faced, and the solutions we implemented to ensure a seamless transition. We discuss our infrastructure, key principles guiding the migration, customizations, scalability achievements, unexpected issues, and our plans for collaboration with the open-source community. The next blog will explore how Uber migrated DSW batch job workloads from Peloton to Kubernetes. Future blogs will explore additional workload and architecture migrations.

The Uber Engineering Blog offers insights, technical deep dives, and updates on the engineering challenges and solutions behind Uber's platform and services. Covering topics such as distributed systems, data infrastructure, and mobile development, the blog provides resources for developers interested in large-scale systems and real-world engineering problems. Developers can learn about Uber's technology stack, engineering culture, and best practices for building scalable and reliable systems.
