The virtual infrastructure is the foundation of an operational SDDC. It contains the software-defined infrastructure, software-defined networking and software-defined storage.

In the virtual infrastructure layer, access to the underlying physical infrastructure is controlled and allocated to the management and compute workloads. The virtual infrastructure layer consists of the hypervisors on the physical hosts and the control of these hypervisors. The management components of the SDDC consist of elements in the virtual management layer itself.
