Desktop virtualization refers to the concept of a single physical machine (desktop) hosting multiple desktops simultaneously being displayed to 2 or more users.
This allows a single PC to cater to about 10 simultaneous user sessions, bringing cost savings for the budget conscious small business IT deployments.
However, each user being has the perception that they are using their own desktop PC with all their installed programs and personalized settings.
One such technology being utilized actively in the Maldives today is
According to a white paper published on the Ncomputing website, “The concept behind the NComputing virtual desktop solution is simple:Today’s PCs are so powerful that only a small fraction of a PC’s power is typically utilized—the rest goes unused.Why not harness the computing power of these underutilized PCs to the benefit of more users?”
Based on the specifications of the module(s) used as well as the combination of software installed, a single PC can host up to 33 simultaneous hosted user desktops.
VSpace, Ncomputing’s patent pending software, supports multiple versions of Windows and Linux operating systems including Windows Server 2008 R2 and Ubuntu 10.4.The software comes with the modules, so need to purchase it separately. The management console allows administrators to set up, configure, remotely monitor and control a user’s session.Virtual desktop settings can be configured centrally, including the ability to lock out connections of USB devices. The software can also selectively virtualize only the necessary elements of the OS and hardware.
An average cost comparison between an Ncomputing solution and an ordinary LAN, done by me is as follows.
Costing amounts are approximate quotations only.
Ncomputing certainly looks like a great product which definitely seals the deal for businesses with that tight IT budget looking to cater to ever changing technology.
However, the following questions still remain to be answered.
- How much bandwidth will be consumed by each module?
- What happens to the user experience when they stream movies and music off the internet?
- How do the modules handle power failures and system crashes?
- How secure is the data being transmitted through the network?
- How will the network be affected when high demand applications are being run, e.g.: AutoCad, Maya, etc.?
