Web Services Policy Framework (WS-Policy) provides a general purpose model and corresponding syntax to describe and communicate the policies of a Web Service. WS-Policy defines a base set of constructs that can be used and extended by other Web Services specifications to describe a broad range of service requirements, preferences, and capabilities.
- WS-PolicyAssertions specifies a set of common message policy assertions that can be specified within a policy.
- WS-PolicyAttachment specifies three specific attachment mechanisms for using policy expressions with existing XML Web Service technologies. Specifically, they define how to associate policy expressions with WSDL type definitions and UDDI entities. They also define how to associate implementation-specific policy with all or part of a WSDL portType when exposed from a specific implementation.

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.
