PLEASE NOTE

The content on this page is from the first draft of the manuscript for the upcoming book "SOA Design Patterns" by Thomas Erl. This version of the manuscript was authored in September, 2007. Since then, the manuscript has undergone significant content and structural changes as a result of an industry-wide review in which hundreds of SOA practitioners participated in addition to SOA vendors and experts from the design patterns community.

You are welcome to use the information on this page for research purposes, but you should assume that most of it will change in the final release of the "SOA Design Patterns" book.

Note also, that as a result of an industry-wide call for participation from December 2007 to February 2008, over 30 new design patterns have been contributed to this book. As they become finalized and are incorporated by the author, concise descriptions will be published on this site, and full descriptions with examples will be made available in the final, printed book.

Due to the volume of new content and changes, the release of the "SOA Design Patterns" book has been postponed to October, 2008. To learn more about the book, visit www.soapatterns.com. To be notified of updates to this site, use the notification form.

Composition Endpoints

How can a composition facilitate an increased range of consumer requirements?

Problem

Service compositions are often created to automate a specific parent task. When variations of this task emerge, new compositions are assembled, leading to a potentially bloated composition inventory.

Solution

A single composition can be equipped with multiple endpoints that accommodate a range of consumers and input values.

Application

Several design techniques can be employed to incorporate new endpoints. The Concurrent Contracts or Denormalized Contract patterns may need to be applied to the composition.

Consequences

To facilitate a range of input values increases the complexity of the composition logic and further increases the governance effort of the composition.

Contributor Notes

This design pattern has been successfully applied, but not yet widely enough to be considered a proven pattern. It will remain a candidate for some time until it has been fully validated and there is a clear need for it.
