In the absence of "hard" definitions.... For me the difference between virtualization and cloud, is a cloud required distributed/redundant storage, so that you have redundancy between sites. Although there are cloud computing products that don't look anything like a convention server, I think until you get to the point "oh London is down so we migrated your service/server to Washington" it is still just virtualization. Whilst I see many advantages to many of the virtualization products on offer, reliably isn't one of them in my experience. I think the complexity in providing a redundant server creates more risk than the reliability of modern server hardware. A cheap Intel/Dell/HP server with mirrored disks will happily give you an uptime till the fans wear out (assuming you swap disk drives as/when they fail). -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
