Desktop virtualization is the use of virtual machines to let multiple network subscribers maintain individualized desktops on a single, centrally located computer or server. The central machine may be at a residence, business or data center. Users may be geographically scattered but are all connected to the central machine by a proprietary local area network (LAN) or wide area network (WAN) or the Internet. Desktop virtualization offers advantages over the traditional model, in which every computer operates as a completely self-contained unit with its own operating system, peripherals and application programs. Overall expenses are reduced because resources can be shared and allocated to users on an as-needed basis. The integrity of user information is improved because all data is maintained and backed up in the data center. Conflicts in software are minimized by reducing the total number of programs stored on any given machine. Benefits of Virtual Desktop Computing • Maintain the Windows desktops and builds from one central location: No need to visit physical machines to install or update software or change configuration. • Support is improved by shadowing sessions and watching the user’s steps: Use RDP tools or the VMware server console to follow what the user is doing when giving Support remotely, or take control of the machine. • Easy recovery, replacement of machines: Blue screen, dead OS, no problem! Simply delete the virtual machine and replace it in Minutes rather than hours. No need to physically collect a machine. • Centralized control, shutdown or restart machines remotely: If a user changes department, simply change the connection profile for that user, allowing them to access the appropriate department build Shutdown or restart a client machine remotely. • Manage your pool of machines: Add or remove virtual desktops as needed in a few minutes. No need to wait for hardware to arrive, when staff changes occur. • Lower cost: Old PCs and low cost thin clients can be used, as the processing is done by the server not the client. No difficult Terminal Server management, 3rd party utilities needed No Terminal Server CAL costs Reduced support and time administering physical desktop
