How It All Works
How do all these pieces—UDDI, WSDL, and SOAP—actually work together to get the work of web services done? Take a look at Figure 10-6.
Figure 10-6. The web service lifecycle
The eight steps in the web service lifecycle are:
Somewhere in the world a client wants to use a web service, so it seeks out a directory service.
The client connects to the directory to discover a relevant service.
By asking the directory service about the services available, the client is able to determine the presence of a service that meets the client's criteria.
The directory contacts the service vendor to check on availability and validity.
The service vendor sends the client a WSDL document.
A proxy class is used to create a new instance of the web service.
SOAP messages originating from the client are sent over the network.
Return values are sent as a result of executing the SOAP message.
This isn't that bad, is it? What's more, Microsoft's WCF and Visual Studio tools make implementing a Service-Oriented Architecture very easy. Let's roll up our sleeves and see how WCF helps you get SOA implementations done fast.
