IaaS Last modified: Friday, May 01, 2009
Short for Infrastructure as a Service, IaaS is defined as computer infrastructure, such as virtualization, being delivered as a service. IaaS is popular in the data center where software and servers are purchased as a fully outsourced service and usually billed on usage and how much of the resource is used — compared to the traditional method of buying software and servers outright. May also be called enterprise-level hosting platform. Sun Microsystems identifies Infrastructure as a Service (IaaS) as one of three layers of cloud computing, in addition to Software as a Service (SaaS) and Platform as a Service (PaaS).
