Web services are a group of closely related, emerging technologies based on an open, Internet-centric infrastructure. They are the driving force that makes corporate portals work, and the best, most economic way of making content and services available to everyone within a corporation, as well as all of its suppliers and customers. And web services is the only area of IT seeing any increase in spending over the foreseeable future. Leveraging Web Services helps CEOs, CIOs, CTOs, and senior managers understand how web services can be applied to their own organizations.
