Scaling Valkey the Right Way: Kubernetes at XL Scale - Sarthak Aggarwal & Madelyn Olson, AWS

This talk explores the use of Valkey, an open-source Redis fork, to meet the growing demand for horizontally scalable and highly available in-memory datastores in cloud-native environments. The speakers, Sarthak Aggarwal and Madelyn Olson from AWS, delve into the intricacies of running large Valkey clusters on Kubernetes, including the essentials of building and operating sharded and replicated clusters across hundreds of nodes. Key topics include cluster bus communication, DNS-based discovery, resource planning, operator-based automation, and strategies to reduce CPU spikes and failover delays. This session offers practical insights for anyone looking to migrate from Redis or start with Valkey in the cloud-native landscape.
