“[Service-Oriented Integration] simplifies system integration by providing a single, simple architectural framework in which to build, deploy, and manage application functionality. Rather than building increasingly larger sets of application functionality, users can build small, finely grained application code that can be published, dynamically located, and bound to without a significantly complicated OO or messaging solution. With simplified components comes reduced cost. Web Services allow users to build complex systems out of very simple components without sacrificing power. This is the key vision that the Service-Oriented Architecture (SOA) brings us.”
