16.5. Summary
Service-oriented architecture (SOA) and the stack of Web services protocols provides a component-oriented paradigm for integrating new and existing applications. The impact of Web services in intra-enterprise computing is for that reason as relevant, if not more, as in B2B scenarios. The SOAP messaging protocols provide on the wire interoperability, and WSDL provides standardized representation of service capabilities. Finally, the WS-Transaction, WS-Security, and other QoS specifications support the level of interaction that everyday business interactions require. |
