Explain the concept of Namespace in Kubernetes and why it is used.

A Namespace in Kubernetes is a logical resource isolator within a single cluster. It allows dividing objects (pods, services, configurations) between different teams or projects without creating a separate cluster.

Why use a Namespace:

• Resource isolation and access control (via RBAC).
• Simplification of organization and object search.
• Limiting resource consumption (CPU, memory) at the namespace level.

For example, in one cluster, you can create a "dev" namespace for development and a "prod" namespace for production, to keep environments separate and manage them independently.
