Improving Response Time and Energy Efficiency in Server Clusters

Raphael GuerraLuciano BertiniJ.C. B. Leite

The development of energy-efficient web server clusters requires the study of different request dispatch policies applied by the central access point to the cluster, the front-end, and/or the application of hardware techniques that allow the best usage of resources. However, energy efficiency should not be attained at the expense of poor response times. This paper describes a technique that tries to balance energy consumption and adequate response times for soft real-time applications in server clusters.
