Virtualization

Server virtualization has begun to prove itself with significant benefits for the server farm, users are continuing to struggle with issues with the desktop. In many organizations, the problem is Vista migration, with the hardware requirements it brings, and the management challenges that distributed desktops have plagued IT with for years, these situations has begun to raise serious questions about desktop strategies for the future. And although upgrading entire PC base to Vista-capable hardware makes more investment burden, desktop virtualization option bring an opportunity to address longstanding desktop management problems.

Terminal services and its extensions have been in production longer than either of the other approaches, offering an early hybrid of client/server computing and mainframe time sharing. This approach, known as server-based computing (SBC), allows multi-user applications to run on a central server, which users typically connect to from a thin client. Users connect from thin and fat clients of many types. This approach is most familiar for applications where a user runs the same multi-user application and nothing. SBC offers the highest ratio of users per server.

Xen virtualization technology (Newly acquired by Citrix), it will be in a good position to offer the centralized desktop computing, via a stronger integration of SBC and virtual clients, with central management of users connecting to whichever is best-suited for a particular need. Where Citrix, Xen and VMware fit today and in the future have an opportunity to lead the upcoming space of centralized desktops management technology.

Some organizations that have successfully deployed server virtualization technology has generally been done using either VMware or one of the Xen-based offerings, more and more users expanding the virtualization out to the desktop. VMware calls its desktop virtualization approach as Virtual Desktop Infrastructure (VDI), Citrix dubbed it Dynamic Data Initiative (DDI), IBM and others use the term virtual clients. user can connect to the virtual machine via a software called as connection broker, using a thin client or browser. These client software’s offer a wide range of functionality and are available from a variety of vendors. By using these clients software’s end user can connect to virtual infrastructure & can use the technology.

The future shows that the upcoming technology will be the virtualization technology, weather it may be VMware or Citrix Xen or Virtual Iron Or Microsoft virtualization or some other X.
