design and development

Although the title is new, this book is based on the authors' 1998 book titled "Web PErformance Metrics, Models and Methods (ISBN 0136938221). This book is more than a minor rewrite - the chapters are in a different sequence, and each has been updated. None of the information that made the older book such a valuable resource was lost in the process. For example, the material on queuing theory and analysis remains, and it among the best written tutorials in print. What has changed includes:

(1) Shifting of focus from client/server and web server environments to web services, with an emphasis on performance characteristics of SOAP and UDDI. Client server issues are still covered because these issues are still germane.

(2) An emphasis on architecture and how performance and capacity fit into a larger picture. Network and server performance characteristics are examined in detail.

What hasn't changed includes the excellent material on performance and benchmarking basics, detailed analysis techniques, and the support for this book that the authors provide on the book's web site. I especially like the Excel spreadsheets that you can download to use in conjunction with material in nearly every chapter.

Overall, this is one more of a series of books on various aspects of performance and capacity management. I also recommend reading their companion book, "Scaling for E-Business: Technologies, Models, Performance, and Capacity Planning" (ISBN 0130863289), which covers the applications level of e-commerce systems and seamlessly complements the material in this book.
