3.2.2 Use Case
A new customer known as Company2 is requesting resources on Company1’s vCloud and has asked the vCloud provider to obtain capacity in the Company1 vCloud. Company2 wants a model that provides the following:
*A defined amount of memory and CPU resources that will be consistent for billing. They have not yet determined the number of virtual machines they will have, but they want consistent billing.
*A dedicated pool of resources to distribute to virtual machines as they see fit when deploying workloads. Based on the initial pool of resources they request, Company1 will also apply a total virtual machine limit to the pool to help Company2 limit overcommitment.
*No fast provisioning, but thin provisioning is acceptable.
Settings can be adjusted as needed to meet the needs of Company2’s vApps.
Based on these requirements, the Reservation Pool model was chosen as the best fit to meet Company2’s needs. This model gives them dedicated resources to start with, and they have control over resource allocation to the virtual machines from vCloud Director.
