Overview
The #1 guide to Web capacity planning -- now completely updated!
- A quantitative analysis of Web service availability
- An integrated coverage of benchmarking, load testing, workload forecasting, and performance modeling of Web services
- Example and case studies show how to use each technique in the latest Web services, portals, search engines, mobile and streaming-media applications
- A quantitative framework for planning the capacity of Web services and understanding their behavior
The world's #1 book on Web capacity planning now covers the latest Web services, e-business, and mobile applications! Capacity Planning for Web Services: Metrics, Models, and Methods introduces quantitative performance predictive models for every major Web scenario, showing precisely how to identify and address both potential and actual performance problems. Coverage includes:
- Web services: protocols, interaction models, and unique performance, reliability, and availability challenges
- State-of-the-art capacity planning methodologies
- Spreadsheets implement the solutions of the models presenteed in the book
- Specific issues and workloads associated with HTTP and TCP/IP protocols
- Benchmarking current performance at system and component levels
From accommodating current usage peaks to defining service provider SLAs, Daniel A. Menasce and Virgilio Almeida cover every aspect of capacity planning — helping you optimize every tradeoff between cost and performance.

Synopsis
In Capacity Planning for Web Services: Metrics, Models, and Methods, two leading Web capacity planning experts introduce quantitative performance predictive models for every major Web scenario — especially the latest Web services, e-commerce, and mobile applications. Discover how to identify and address potential performance problems, accommodate usage peaks, define service provider SLAs, benchmark effectively — and optimize every trade-off between cost and performance.
Editorials
From Barnes & Noble
The Barnes & Noble ReviewThe 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)
