Anything as a Service

Anything as a Service (XaaS) is a broad term used for describing the vast ecosystem of different cloud computing technologies and resources delivered by a vendor as an integrated service over the internet. There are three main categories of cloud computing services — Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). The XaaS model is an extension to these three categories, further expanding the types of services that can be provided by vendors.

Examples
