about this example

Kubernetes clusters are the foundation of modern, scalable application deployment. This diagram demonstrates:

Control Plane Components: The central management tools including the API server, scheduler, controller manager, and etcd.
Node Structure: The workings inside a node showing kubelet and kube-proxy and their interaction with containers.
Cloud Integration: Interaction between the cluster’s control plane and the cloud provider API for resource management.
Pod Management: How pods are managed on each node, showcasing the Container Runtime Interface (CRI) and actual pod instances.

When to use

Infrastructure Design: When architecting the infrastructure for containerized applications, ensuring best practices in cluster setup.
Training Purposes: To train new engineers on the components and interactions within a Kubernetes cluster.
Cloud Transition: For teams transitioning from traditional hosting to cloud-native services, providing a clear structure of Kubernetes on a cloud provider.
