Uber has successfully migrated its compute platform from Apache Mesos to Kubernetes, marking a significant evolution in its infrastructure. This change encompassed migrating thousands of microservices while prioritizing service reliability during the transition. The engineering team emphasized a structured and careful process that included a dual-stack approach to minimize risks and maintain operational coherence. The migration, ambitious in scope, was part of Uber’s strategic shift towards a more cloud-native architecture, ensuring that all critical services experienced zero downtime during the shift.
"This migration was not just a technology change, but a complete reimagining of how we operate our compute infrastructure."
The engineering teams developed a sophisticated migration framework that allowed for gradual service transitions while maintaining full backward compatibility with existing Mesos-based services.
The migration strategy centered on several key principles: maintaining service reliability throughout the transition, ensuring seamless integration with existing tools and workflows, establishing robust monitoring and observability capabilities.
Uber's approach to the Kubernetes migration was methodical and risk-averse, prioritizing service reliability above migration speed.
