Scaling Kubernetes Networking Beyond 100k Endpoints

Explore the challenges and solutions for scaling Kubernetes networking beyond 100,000 endpoints in this informative conference talk. Dive into the design and implementation of EndpointSlices, and learn how they have significantly improved network scalability in Kubernetes. Discover the process of profiling key components in the Kubernetes codebase to identify optimization opportunities. Gain insights into real-world performance metrics from large clusters with over 100,000 endpoints. Understand the current pain points, existing Endpoints API limitations, and the impact of the new EndpointSlices approach. Follow the journey from identifying scalability bottlenecks to implementing solutions that dramatically increase the capacity for network endpoints in Kubernetes clusters.
