Customer workloads are running in organization VDCs which are provisioned inside a provider VDCs. Provider VDCs are mapped to vSphere resource pools or to clusters. One provider VDC can be mapped to multiple resource pools / clusters and create an elastic VDC, with the exception of the reservation type of Org VDCs. When a customer outgrows its organization VDCs and requires its extension, the request can be granted only if there is available capacity inside the provider VDCs. If there is no capacity available, a new organization VDC is carved up from another provider VDC and must be provisioned. This can make the customer VM deployment more difficult because the customer has to manage the capacity of multiple organization VDCs.
