About This Architecture
High-availability Kubernetes control plane architecture with three master nodes behind a load balancer, each running API Server, Scheduler, and Controller Manager. Shows a dedicated etcd cluster with Raft consensus, leader election, and data replication for fault tolerance. Fork this diagram on Diagrams.so to customize the number of control plane nodes or add stacked vs external etcd topology for your HA cluster. Source: https://kubernetes.io/docs/concepts/architecture/
