4.1. Namespace Create
A Namespace is a logical unit used to partition a cluster.
It is typically created per project phase or per service.
Example:
- When created per project phase: Development, Staging, Production
- When created per service: Authentication Service, Payment Service, Reservation Service, etc.
The Namespace creation and management feature is only accessible to Cloud Z DB platform administrators with 'cluster-admin' privileges.
