Designing scalable and secure systems has always made good common sense; given events in the past few years, it has become imperative. Xu (Wayne State U.) brings these interrelated issues down to a manageable size by addressing each topic as an exercise, explaining how to make the most efficacious decisions for each situation through rigorous mathematical modeling and analysis, simulation, and practical implementations. His topics include server clusters and network load balancing, resource management with QoS in mind, server capacity planning, Web caching and pre-fetching, the P2P overlay network, mobile code and security, and mobility support for adaptive grid computing.
