Virtualisation 'crucial for cloud computing'

Virtualisation technology plays a "key" role in the use of cloud computing, according to one IT expert.

Writing for the Wall Street Journal, William M Bulkeley explained that virtual servers allows a single computer to function as multiple virtual servers running many operating systems and applications.

He said that the technology was crucial to the development of the cloud because it has no dedicated computers.

"Each one can run many software applications at the same time, with processing power and storage shared among applications depending on demand," he added.

Mr Bulkeley added that cloud computing enables firms to tap into raw processing power, storage, software applications and data from large data centres over the internet.

Last week, experienced IT manager David Davis explained in a VMWare white paper that virtualisation not only helps reduce costs, but also bolsters business continuity planning
