Kubernetes cluster architecture is based on a distributed system design.

A cluster is divided into two main parts:

• Control Plane (manages the cluster)
• Worker Nodes (run applications)

This separation allows Kubernetes to:

• Scale workloads easily
• Recover from failures automatically
• Manage applications in a declarative way

A typical flow:

• User sends request (kubectl / API)
• Control Plane processes it
• Worker Nodes execute workloads (Pods)

The architecture ensures:

• High availability
• Fault tolerance
• Automated workload scheduling
