VerifiedKubernetes adopts a control plane and data plane separation architecture, including etcd for storing desired state, API Server as the entry point for state changes, Controller Manager running control loops, and Scheduler for scheduling Pods.79% similarUnverifiedThe control plane is a concept originating from network engineering and distributed systems, referring to the system layer responsible for managing, configuring, and coordinating data flows, as opposed to the data plane that processes data; in cloud-native architecture, Kubernetes' API Server is a typical control plane component.73% similarUnverifiedKubernetes adopts the idea of separating the control plane from nodes, with control components such as the API Server and Scheduler separated from the nodes that run Pods.73% similarUnverifiedKubernetes' API Server is essentially a control plane responsible for scheduling decisions, while the kubelet on each node is the data plane responsible for actual execution.72% similarUnverifiedKubernetes中etcd存储集群期望状态，API Server作为唯一控制入口，Controller Manager持续调谐实际与期望状态差距，kubelet负责执行指令71% similar
