*[[w:Cloud computing]] multiple [[w:abstraction]] layers 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.

= Cloud computing =
*'''[[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.

== Things as a service ==
:* '''[[w:Infrastructure as a service]] (IaaS)'''
:* [[w:Platform as a service]] (PaaS)
:* '''[[w:Software as a service]] (SaaS)'''
:* [[w:Network as a service]] (NaaS)
:* [[w:Storage as a service]] (STaaS)
:* [[w:Security as a service]] (SECaaS)
:* [[w:Data as a service]] (DaaS)
:* [[w:Desktop as a service]] (DaaS - see above)
:* Database as a service (DBaaS)
:* [[w:Test environment as a service]] (TEaaS)
:* [[w:API as a service]] (APIaaS)
:* [[w:Backend as a service]] (BaaS)
:* Integrated development environment as a service (IDEaaS)
:* Integration platform as a service (IPaaS), see [[w:Cloud-based integration]]
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.
