Everything as a service
Everything as a service(EaaS, XaaS,  *aaS) is a concept of being able to call up re-usable, fine-grained software components across a network. It is a subset of cloud computing. The most common and successful example is software as a service (SaaS), but the term as a service has been associated and used with many core components of cloud computing including communication, infrastructure, data and platforms.
