In addition to these fault surviving technology cloud computing is very w:ecologically efficient as several, even tens of w:virtual servers can live on one physical machine instead of expensive server hardware sitting idly as the load is much lower then the total processing power by a factor of 10x or so. The w:Microsoft Office 2010 at HH is from-cloud. With cloud computing w:Infrastructure as a Service is feasible.
