Design Solutions for SOAP/WSDL and RESTful Web Services

Web services have been put into practical use for many years. In this time developers and architects have encountered a number of recurring design challenges related to their usage. We have also learned that certain design approaches work better than others to solve certain problems. This site is for software developers and architects who are currently using web services or are thinking about using them. It was created as the companion site for a book on Service Design Patterns to be released by Addison Wesley on the Martin Fowler Signature Series in October 2011. The goal of the book and this site is to acquaint you with some of the most common and fundamental web service design solutions, and to help you determine when to use them. All of the concepts discussed here are derived from real-life lessons.

Service developers are confronted with a long list of questions:

These are just a few of the questions that service developers must answer. This site provides a quick overview of several design patterns from the book that address these questions. The patterns you will find here may be used to create web services that either leverage SOAP/ WSDL or follow the REST architectural style.
