What is Anything-as-a-service?

Anything-as-a-service is a term used to refer to the varied and diversified services delivered over the internet through cloud computing technology.  It is a departure from traditional model wherein everything was stored on the local drive.

In popular literature, Anything-as-a-service is denoted as XaaS, the X denotes everything. Xaas can include all or one of software-as-a-service (SaaS) to storage-as-a-service, desktop-as-a-service (DaaS), disaster recovery-as-a-service (DRaaS), network-as-a-service (NaaS), infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS), and even emerging services such as marketing-as-a-service and healthcare-as-a-service. Anything as a service is the next frontier and is gaining increasing prominence due to advancements in cloud computing technologies.
