User communities are rapidly transitioning their ''Traditional desktops'' that have dedicated hardware and software installations into ''Virtual Desktop Clouds'' (VDCs) that are accessible via thin-clients. To allocate and manage VDC resources for Internet-scale desktop delivery, existing works focus mainly on managing server-side resources based on utility functions of CPU and memory loads, and do not consider network health and thin-client user experience. Resource allocations without combined utility-directed information of system loads, network health and thin-client user experience in VDC platforms inevitably results in costly guesswork and over-provisioning of resources. In this paper, the authors develop an analytical model viz., ''Utility-Directed Resource Allocation Model (U-RAM)'' to solve the combined utility-directed resource allocation problem within VDCs.
