ABSTRACT
Now with the arrival of clouds, there is an unprecedented transition on the service-enablement front. e SOA paradigm introduced so£ware services; with clouds it is possible to have network-accessible hardware services. In other words, every IT resource (virtual and physical IT modules) can be expressed and exposed as a service. e service view has signiž- cantly reduced IT complexity (design, development, articulation, management and, žnally, use) through the logical separation of interface and implementation. As a result, all kinds of technological heterogeneities are wiped out in one stroke. e restraining and constricting dependencies of so£ware vanish and, thereby, a series of incisive and incredible innovations in the form of service patterns, platforms, practices, prescriptions, and processes ³ourish in an open and uncontaminated environment. A stream of novel service providers have cropped up across industry segments with the overwhelming adoption and adaption of the venerable service idea.
