The values can be obtained for at least a portion of the resources. The one or more categories can be based on quantifiable properties associated with the resources. The provisioning manager can determine a priority score for each of the at least a portion of the resources. The provisioning manager can determine a resource from the at least a portion of the resources to be distributed to the requester, where the determination can be based at least in part on the priority score for the resource.
