A provisioning server delivers operating systems to more than one virtual machine in different subnetworks. Since one provisioning server can be used for multiple subnetworks, this reduces the need to build, license, and support a provisioning server or a provisioning server farm for each subnetwork. This eliminates additional Infrastructure Software licensing; reduces additional effort to implement and maintain more provisioning servers; increases flexibility to add additional subnetworks; and scales a provisioning server farm to meet demand by adding servers.
