What is the difference between resource allocation and resource provisioning?

• Resource allocation is the process of reservation that demarcates a quantity of a resource for a tenant’s use.
• Resource provision is the process of activation of a bundle of the allocated quantity to bear the tenant’s workload.

Immediately after allocation, all the quantity of a resource is available. Provision removes a quantity of a resource from the available set. De-provision returns a quantity of a resource to the available set. At any time:

Allocated quantity = Available quantity + Provisioned quantity
