An industry view on service-oriented architecture and Web services

Web services are autonomous software systems identifiable by URIs that can be advertised, located, and accessed through standard-based XML messages (e.g. SOAP, WSDL, and UDDI) and transmitted via Internet protocols. Web services encapsulate application functionalities and information resources, and make them available through programmatic interfaces, as opposed to the typical interfaces provided by traditional Web applications specifically for manual interactions [1]. Web Services integration enables a dynamic ebusiness model that fosters collaboration with heterogeneous business services and opens the doors for new business opportunities. A service-oriented architecture (SOA) is an application framework that takes everyday business applications and breaks them down into individual business functions and processes, called services [2]. With the widely acceptance and adoption of SOA that wraps software resources over the network as services and provides a standard-based IT infrastructure, we anticipate and envision more opportunities for the software industry to adopt a Service business model. In this talk, we will discuss dynamic Web servicesintegration and show various patterns whenimplementing on demand integrations. We willpresent guidelines for applying the SOA approach toseveral industrial business scenarios and for selectingWeb services technologies. We will conclude withour view about the trends and directions of WebServices and SOA in the on demand world.References [1] J. Chung, K. Lin, R.
