Anything as a service (XaaS) is a term that describes a broad category of services related to cloud computing and remote access. With cloud computing technologies, vendors offer companies different kinds of services over the web or similar networks. This idea started with the basic software as a service (SaaS) with cloud providers offering individual software applications. Other terms like infrastructure as a service (IaaS) and communications as a service (CaaS) were added as cloud services evolved. With so many different kinds of IT resources now delivered this way, XaaS is a somewhat ironic term for the proliferation of cloud services.
