3. Choosing a vCloud Consumption Model : 3.2 vCloud Director Allocation Models
3.2 vCloud Director Allocation Models
Allocation models define how resources are allocated to an organization’s virtual datacenter and how resources are consumed when vApps are deployed.
Allocation models are differentiated by how resources are reserved or limited. A limit can be placed at the level of a virtual machine or a resource pool. To guarantee resources to a virtual machine or to an entire resource pool, vCloud Director sets a reservation or not depending upon the allocation models used. The following are vCloud allocation models:
*Allocation Pool.
*Pay As You Go.
*Reservation Pool.
The following figure shows the vCloud Director screen for selecting an allocation model.
