Learn how to deploy fault-tolerant and scalable Kubernetes clusters using distributed PostgreSQL in this technical conference talk from KubeCon. Explore the evolution from Etcd to modern relational databases for Kubernetes cluster data management, with a focus on practical implementation. Discover how Kine integrates with Kubernetes architecture to enable relational database usage for cluster metadata management. Follow along with the step-by-step process of deploying Kubernetes on a single-server PostgreSQL instance before scaling to a multi-node PostgreSQL configuration that can handle zone and region outages while supporting thousands of nodes. Master the transition from traditional Etcd-based clusters to more robust PostgreSQL-based solutions that offer enhanced availability and scalability characteristics for various Kubernetes workloads.
