Kubernetes Architecture

Welcome to Kubernetes! Before we dive into commands, we need to understand the big picture. Kubernetes is an orchestration platform that abstracts away hardware and manages containerized applications. It is divided into two main parts: the Control Plane and the Data Plane (Nodes).
