Web Services Eventing (WS-Eventing) provides a protocol that allows Web Services to subscribe to or accept subscriptions for event notification messages. This specification defines a protocol for one Web service (called an "event sink") to register interest (called a "subscription") with another Web service (called an "event source") in receiving messages about events (called "notifications"). To improve robustness, the subscription is leased by an event source to an event sink, and the subscription expires over time. An event source may allow an event sink to renew the subscription.

by 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.
