*'''[[w:Cloud computing]]''' ( [[w:fi:Pilvilaskenta]] ) is a major pleasantifier of information technology systems acquisition and operation hassle and costs. Prices start as low as 15€ / VPS-from-cloud ( virtual private server ) with full [[w:root]] access. Additionally cloud computing is ecological. Think of a business buying a big physical server which is then utilized to 10% of it's maximum capacity whereas in cloud computing you can thanks to [[w:Virtualization]] technologies have much better utilization rates for actual physical devices.

:: In cloud computing [[w:abstraction layer|abstraction layer]]s provide ability to move virtual servers around the cloud. It can anticipate breaking down of single physical components and move the services to a sound, functional piece of server hardware in advance to the physcial component breaking up.

In addition to these fault surviving technology cloud computing is very [[w:ecological]]ly 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.

In the [[w:business model]] using software as a service, users are provided access to application software and databases.  The cloud providers manage the infrastructure and platforms on which the applications run.  SaaS is sometimes referred to as “on-demand software” and is usually priced on a pay-per-use basis.  SaaS providers generally price applications using a subscription fee.
