# Key concepts

Key concepts describe the tenant types and isolation principles that governs the HPE Morpheus Enterprise multi-tenancy model.

The HPE Morpheus Enterprise multi-tenancy is built around three tenant types, that is primary tenant, parent tenant, and sub tenant. Each tenant operates as a fully isolated environment, with resources, users, and workloads kept separate from peer tenants. Access to resources across tenant boundaries is controlled through visibility settings and explicit assignments from higher-level tenants.
