The virtual infrastructure is the foundation of the SDDC. It contains the software-defined infrastructure, software-defined networking and software-defined storage. The virtual infrastructure layer runs the operations management layer and the Cloud Management Platform.

In the virtual infrastructure layer, access to the underlying physical infrastructure is controlled and allocated to the management and tenant 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, along with elements in the cloud management layer, or in the operations management, business continuity, or security areas.

The virtual infrastructure layer provides virtualization of compute resources, storage and networking. It hosts the virtual machines of the management components of the SDDC and the tenant workloads.
