From P2P to Web Services and Grids Peers In A Client/Server World

"From P2P to Web Servicesnbsp;and Grids"nbsp;provides a comprehensive overview of emerging distributed-systems technologies. It covers peer-to-peer (P2P) systems, which have revolutionized the way we think about distributed computingnbsp;and the internet, alternative solutions, most notably web servicesnbsp;and Grid computing, but also other technologies, such as client/server based systemsnbsp;and distributed-object technologies.A wide range of middlewarenbsp;and application-based technologies are covered, such as Jxta, Jini, Globus, Web services, OGSA, WSRF, SOAP,WSDL, Napsternbsp;and Gnutella, with emphasis given on the architecture employednbsp;and security model chosen. Each technologynbsp;and its capabilities are analyzed in the context of the degree of centralization or decentralization they employ.A resulting taxonomy is created giving a context in which to consider the most advancednbsp;and broad ranging distributed systems available today,nbsp;and provides an essential reference text for designing new distributed systems.
