Kubernetes architecture: control plane, worker nodes, kubelet, etcd

The Kubernetes Control Plane

Kubernetes is the de facto orchestration platform for cloud-native telecom deployments. The control plane consists of several components working together to manage the cluster state. The API server is the central hub through which all communication flows, exposing a RESTful interface for cluster operations. etcd is a distributed key-value store that persists the desired state of every object in the cluster. The scheduler assigns pods to nodes based on resource requirements and constraints, while controller managers run reconciliation loops that continuously drive actual state toward the…
