The virtual infrastructure is the foundation of an operational SDDC.

Within the virtual infrastructure layer, access to the physical underlying infrastructure is controlled and allocated to the management and tenant workloads. The virtual infrastructure layer consists primarily of the physical hosts' hypervisors and the control of these hypervisors. The management workloads consist of elements in the virtual management layer itself, along with elements in the cloud management layer and in the service management, business continuity, and security areas.
