Resource pools represent a unit of CPU, memory, and storage that are portioned from the shared infrastructure pool. These resource pools are attached to Provider VDCs that in return are the abstracted pools of resources that tenants consume through Organization VDCs. The resources of a Provider VDC, and hence the resources available to tenants, can be scaled by scaling the underlying resource pool to meet future resource demands.

By mapping different Provider VDCs to different resource pools backed by different vSphere host clusters, CSPs can meet different SLAs as per tenant resource requirements.
