Abstract: In one implementation, a host provides virtualized computing to one or more customer networks. The virtualized computing may include hardware virtualization quantified in the resources of the virtual machines, services virtualization quantified in the quantity or types of services performed on host, or processing virtualization quantified by process occurrences. When the host receives a request for computing virtualization from a user device, the host derives an authentication value and accesses a virtualization service level from a memory. The host is configured to deliver the computing virtualization to the user device according the virtualization service level.
