The more your company depends upon web applications and web services, the more you need to be able to quantify and predict the performance of your Internet infrastructure on an end-to-end basis. Intuition and rules-of-thumb are no longer enough: You need a proven methodology and specific formulas. Daniel A. Menascé and Virgilio A. Almeida have been studying web performance for years, and they've just written the definitive book on the subject.
Capacity Planning for Web Services begins by introducing the fundamental concepts of web capacity planning and service levels and showing how rapid evolution in web workloads can impact performance. The authors review the performance characteristics of key web/Internet protocols: TCP/IP, Ethernet, and HTTP, as well as important newcomers such as SOAP and WSDL.
Next, they identify every potential area of delay involved in the retrieval of a web page and show how to compute service times at disks, disk arrays, networks, and routers. Menascé and Almeida then go beyond traditional web apps to address the distinctive characteristics of web services, including wireless services.
Capacity Planning for Web Services then introduces a step-by-step methodology for identifying the most cost-effective web services infrastructure. You'll learn how to capture accurate data and construct accurate workload models; how to use benchmark results to complement your capacity planning; analyze the performance of intranets and web sites; how to model availability and reliability; and how to adapt your performance models to specific issues, such as burstiness or streaming media.
If you're ready to stop guessing about web performance, this is the book you've been searching for. (Bill Camarda)
