Architecting a vCloud Director Solution : Deployment Model Considerations : 3.1 Service Offerings : 3.1.5 Consumption Models : 3.1.5.2 Virtual Private Cloud
   
3.1.5.2 Virtual Private Cloud
The customer buys a chunk of resources in terms of virtual private cloud (VPC) consisting of compute (CPU and memory), storage, and networking. Inside the VPC, they deploy workloads up to the total capacity of resources purchased. This consumption model is beneficial for steady workloads because the customer knows their needs and can commit to buying the resources for minimum period of time (usually at least a month).
The oversubscription of resources is managed by the provider and the customer has no control over it. The size of VPC can be arbitrary from as small as a portion of one host to as large as multiple vSphere clusters, thanks to the sharing of underlying physical and vSphere virtual infrastructure among different tenants.
This offering directly maps to the Org VDC Allocation Type allocation model.
