WS Track - The Role of Policy in Web Services Integration - It's More Than Just Security

How Does A Web Service Behave When Discovered, Invoked And Programmed Right Into The Business Logic?

Too often today the preferences, terms, and conditions describing how a Web service behaves when discovered and invoked is programmed right into the business logic. Hard-coding this behavior logic however introduces cost, complexity, and rigidity into a Web services architecture. A better approach is to abstract a Web services "usage policy" out of code where this metadata can be managed as need be. This session introduces the concept of Web Services Policy and describes how the construct can be used to implement a more customized and versatile Web service infrastructure.
