Enterprises frequently have to deal with part of their infrastructure that
doesn't have the privilege of uninterrupted connectivity. Such system
environments designed using Service Oriented Architecture (SOA) need a way to
manage uncertain connectivity. SOA as an architectural paradigm depends on a
set of services providing business functionality. These services may be
distributed over different domains or geographical boundaries. SOA,
characterized by independent and self-sufficient services primarily needs to

need a different methodology for testing in a real-world scenario. The
UI-less nature of Web Services presents a significant challenge in testing
such applications. The wh... (more)
Most organizations that have tried have been successful in implementing a

using a staggered approach. The rewards reaped come in the form of low-cost
maintenance and agility in their business, along with reusable and
self-contained ser... (more)
