Citrix Provisioning Services (PVS) allows you to have a single instance image management of your XenApp and/or XenDesktop VMs – otherwise known as desktop management nirvana! This means you only have to update a single image which is then streamed to hundreds, or thousands of desktops. No more unreliable software deployments across your desktop fleet, just install the new software once on the master image and when the PVS clients (‘target devices’ in PVS speak) reboot, they get the updated image with the new software.
