Produktbeschreibung
This edition provides a comprehensive overview of emerging distributed-systems technologies has been significantly enhanced extended into the many new state-of-the-art infrastructures technologies that have appeared since the successful 1st edition. The focus is also broadened, retaining the technical aspects, but including historical contexts for each of the technologies.This edition fills in the gaps includes an additional 13 chapters on new higher popular technologies, including bittorrent, OGSA/WS-RF, workflow technologies, portals& enhanced deployment sections for the new technologies - taking a more applied approach. Further background issues such as state/stateless services& describingvarious possible communication methods from history the basic connectivity are also presented.
Over the past several years, Internet users have changed in their usage p- terns from predominately client/server-based Web server interactions to also involving the use of more decentralized applications, where they contribute more equally in the role of the application as a whole, and further to d- tributed communities based around the Web. Distributed systems take many forms, appear in many areas and range from truly decentralized systems, like Gnutella, Skype and Jxta, centrally indexed brokered systems like Web s- vices and Jini and centrally coordinated systems like SETI@home. From P2P and Grids and Services on the Web Evolving Distributed Communities provides a comprehensive overview of the emerging trends in peer-to-peer (P2P), distributed objects, Web Services, the Web, and Grid computing technologies, which have rede ned the way we think about d- tributed computing and the Internet. The book has four main themes: d- tributed environments, protocols and architectures forapplications, protocols and architectures focusing on middleware and nally deployment of these middleware systems, providing real-world examples of their usage.
Rezensionen
From the reviews:

"Provides rich background information to beginners entering this subject area. ... The diagrams ... are clear-cut, as are the snippets of codes. There are hardly any errors throughout the book. ... covers a broad and coherent range of distributed-computing techniques ... . People with different programming abilities, even those who have never written a single line of code ... learn a lot from it. ... recommend the book to anyone interested in distributed computing, especially students in the field of distributed computing ... ." (Haoyang Che, THE COMPUTER JOUNAL, Vol. 48(3), 2005)

"Specialists working on different types of novel distributed computing systems will like this book. It will be of interest, for instance, to peer-to-peer (P2P) developers who want to know how a somewhat similar idea of grid computing works, and the other way around. It would also be a good choice for laymen who are looking for a good textbook on these topics. ... For people involved with the Internet, this book is a really enjoyable journey through a number of hot topics." (Piotr Cholda, ACM Computing Reviews, July, 2009)
