The following Venn diagram illustrates the relationships among Web Services, service-oriented architecture (SOA), and Cloud Computing. Web Services encapsulates Cloud Computing in this diagram because Cloud Computing uses Web Services for connections (you might find exceptions, but they are rare). It is possible, however, to use Web Services in situations other than Cloud Computing. Such use of Web Services may be part of a service-oriented architecture, but it may not. Web Services could be simply be a connection. Finally, it is possible to have a service-oriented architecture and not use Web Services for connections.

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.
