A service-oriented architecture is fundamental to many new IT applications, from web development to social software and cloud computing. The same principles can be applied to every aspect of the service-oriented enterprise ¿ not just in IT. In this book, yoüll explore how an enterprise architecture and viable services can link together to create a simpler yet far more powerful view of the enterprise, as a dynamic, unified whole. You can use the ideas, principles and methods described here in business transformation, workflow mapping, system design and much else besides, in every type of enterprise - including those in which there may be little or no IT at all. Step by step, yoüll walk through the basics of service-oriented architectures, the four key categories of services and how they connect, and how all of this comes together in real-world service design, implementation and operations.

The result of careful and meticulous research, this stylishly-written biography of infamous blues musician Robert Johnson reveals the real story behind the mythical talent that made him a musical legend. According to some, Robert Johnson learned guitar by trading his soul away to the Devil at a crossroads in rural Mississippi. When he died at age 27 of a mysterious poisoning, many superstitious fans came to believe that the Devil had returned to take his due. This diligent study of Johnson's life debunks these myths while emphasizing the effect that Robert Johnson, said to be the greatest blues musician who ever lived, has had on modern musicians such as Eric Clapton and the Rolling Stones and fans of the blues. Tom Graves, a master of what Ernest Hemingway called "the true sentence" and the telling detail, pieces together the fragments of the jagged, elusive puzzle that is Robert Johnson.
