XaaS (anything as a service)

What is XaaS (anything as a service)?

XaaS is a collective term said to stand for a number of things including "X as a service," "anything as a service" or "everything as a service." The acronym refers to an increasing number of services that are delivered over the Internet rather than provided locally or on-site. XaaS is the essence of cloud computing.

The most common examples of XaaS are Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). The combined use of these three is sometimes referred to as the SPI model (SaaS, PaaS, IaaS). Other examples of XaaS include storage as a service (SaaS), communications as a service (CaaS), network as a service (NaaS) and monitoring as a service (MaaS).

Following the convention of pronouncing "SaaS" as "sass," "XaaS" is sometimes pronounced as "zass."

Wouldn't it be easier and to take all of these 'aaS' acronyms and just call them 'aaSS', meaning "as a Service System". I have seen a lot of people in the IOT community using 'aaSS' recently instead of detailing every acronym; IaaS, HaaS, SaaS, EaaS (emulation). Since all of this is fairly new everyone is trying to coin a phrase, but aaSS is the one that makes the most sense across the board.
