Service Models
Cloud computing providers offer their services according to several fundamental models: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) where IaaS is the most basic and each higher model abstracts from the details of the lower models. Other key components in XaaS are described in a comprehensive taxonomy model published in 2009, such as Strategy-as-a-Service, Collaboration-as-a-Service, Business Process-as-a-Service, Database-as-a-Service, etc. In 2012, network as a service (NaaS) and communication as a service (CaaS) were officially included by ITU (International Telecommunication Union) as part of the basic cloud computing models, recognized service categories of a telecommunication-centric cloud ecosystem.

Famous quotes containing the words service and/or models:
“We could not help being struck by the seeming, though innocent, indifference of Nature to these men’s necessities, while elsewhere she was equally serving others. Like a true benefactress, the secret of her service is unchangeableness. Thus is the busiest merchant, though within sight of his Lowell, put to pilgrim’s shifts, and soon comes to staff and scrip and scallop-shell.”
—Henry David Thoreau (1817–1862)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
