The Web Services Notification (WSN) defines a set of specifications that standardize the way Web Services interact using the notification pattern. In the notification pattern, a Web Service disseminates information to a set of other Web Services, without having to have prior knowledge of these other Web Services. Characteristics of this pattern include:
- The Web Services that wish to consume information are registered with the Web Service that is capable of distributing it. As part of this registration process they may provide some indication of the nature of the information that they wish to receive.
- The distributing Web Service disseminates information by sending one-way messages to the Web Services that are registered to receive it. It is possible that more than one Web Service is registered to consume the same information. In such cases, each Web Service that is registered receives a separate copy of the information.
- The distributing Web Service may send any number of messages to each registered Web Service; it is not limited to sending just a single message.

Web Services, Service-Oriented Architectures, and Cloud Computing: The Savvy Manager's Guide (Second Edition)
by Douglas K Barry with David Dick
This is a guide for the savvy manager who wants to capitalize on the wave of change that is occurring with Web Services, service-oriented architecture, and—more recently—Cloud Computing. The changes wrought by these technologies will require both a basic grasp of the technologies and an effective way to deal with how these changes will affect the people who build and use the systems in our organizations. This book covers both issues. Managers at all levels of all organizations must be aware of both the changes that we are now seeing and ways to deal with issues created by those changes.
