Abstract: Systems and methods are described for provisioning a desktop interface at a cloud service provider. An application service is introduced that selects a cloud service provider for provisioning a virtual machine (“VM”) that hosts the desktop interface. In an example, a user can request access to a virtual desktop from a client device. The application service can retrieve network latency data from multiple cloud service providers and select the provider with the lowest network latency for the client device. In some examples, the application service can select the cloud service provider on additional factors, such as the cost of provisioning the VM at each cloud service provider. The application service can provision the VM at the selected cloud service provider and facilitate access to the virtual desktop for the client device.
