Application virtualization lets IT manage a single instance of each application in an application hub in the data center. Applications are then delivered via application streaming directly to Windows PC’s for off-line application virtualisation or run on high-powered servers in the data center for on-line application virtualisation on any device or operating system. An example is Citrix's XenApp which allows thin clients or Linux, MacOSX, or Windows run Microsoft Office without a local installation. Other solutions include the open source alternative Ulteo Virtual Desktop which provides the same functionality as Citrix over WAN or LAN.
