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.

This can adversely affect the organisation’ operations if a service provider makes significant changes to its policies or the entire business model.
