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.
