3.1 Chapter Overview

  • Web Services, which are units of business services and components , are positioned as the next IT strategy for enterprises . The enabling technologies are built on top of XML. They are also referenced as " XML Web Services. "

  • The Web Services technology stack includes the transport layer (for example, SOAP over HTTP), a service description language (for example, WSDL), transaction routing (for example, ebXML Message Service), and service negotiation (for example, ebXML Business Process).

  • Web Services have many similarities and associations with CORBA. Some see Web Services technology as a reincarnation of Application Service Provider and CORBA.

  • Microsoft's version of Web Services is .NET, with C# as one key development language. Sun, IBM, and other technology vendors are using Java as the service enabler for Web Services.

  • To enable your applications to be Web Services, you do not need to rewrite them in Java or C#. There are four simple steps to transform your existing applications into Web Service.

  • Web Services solutions are still in the "technology-hype" stage.

  • There are, however, at least three public UDDI nodes and numerous Web Services directories that enlist pilot Web Services applications.

  • Many technology and solution vendors have already shipped their Web Services-enabled products. Consumers may not even know Web Services are already in action.
