A newly created organization has no VDCs in it. A system administrator can use system resources to create VDCs in an organization. A system administrator can also define VDC templates, share them with organizations and grant organization members the right to use the templates to create VDCs in their organization.
An organization virtual datacenter (organization VDC) is a deployment environment for virtual systems owned by the containing organization, and an allocation mechanism for resources such as networks, storage, CPU, and memory. In an organization VDC, computing resources are fully virtualized, and can be allocated based on demand, service level requirements, or a combination of the two.
