=====Kubernetes Architecture Overview=====

====Control Plane (management layer)====
  * **kube-apiserver:** central access point for all operations
  * **etcd:** persistent state store
  * **kube-scheduler:** assigns Pods to nodes
  * **controller-manager:** maintains cluster state (replicas, jobs, nodes)
  * **cloud-controller-manager:** cloud provider integration
====Node Components (worker layer)====
  * **kubelet:** ensures Pods run as instructed
  * **kube-proxy:** networking and load balancing rules
  * **container runtime:** runs containers
====Networking====
  * Each Pod gets a unique IP
  * Pods can reach each other without NAT
  * Services provide stable virtual IPs
  * CNIs implement the network model
====etcd====
  * Source of truth for the entire cluster
  * Stores cluster configuration, secret data, and runtime state
