Advantages and Disadvantages of Hosted Virtual Desktops

By Adam G. Glover


When it comes to businesses at the forefront of technology, it's very important to look for ways in which you can meet the requirements of your office, while also saving money. Something that people are turning to is a hosted virtual desktop. This means that you don't have 'local software' on your computer, but instead connect to a server for your software requirements, even your OS. The server is now the thing that runs your computers, and supplies them with the applications they need.

This can be great because of its money saving potential. The computers in the network become 'thin-clients,' meaning that they don't need lots of processing power to do what's necessary anymore. Because the server is the thing that's doing all the work, you don't have to invest in powerful computers for your office, and don't have to update your network as often. The fact that the computers are lower spec, and using less processing power, also saves you lots of money on energy demands.

Better access across your network of computers means better desktop support. This translates to you spending less time and money on repairs. You can easily swap out the 'thin-client' PC and continue work. The data isn't lost, and time isn't lost copying and backing up data. This can also lead to easier admin processes, as everything from patches to new software happens at server level with a superior administrator. All in all it's a very sensible way of running a complex system.

The cons include the network bandwidth required, and that all of your eggs are in one basket. Network upgrades could be required to meet such massive bandwidth needs. This is the Achilles heel of the whole thing. Complex graphics and even printer and scanner applications can be limited due to the issue of bandwidth. Limited storage can also be a problem for similar reasons. In addition, an obvious issue is relying on one server that could potentially go wrong.

And while there are backups, it can also be unnerving to invest all of your workplace's running potential in one server, so give it some thought before committing to this potentially money-saving overhaul.
