Load Forecasting for Dynamic Configuration of Web Server Clusters
Abstract
Nowadays, there is a growing awareness about green computing in computer systems. A major source of energy demand in these systems are web server clusters. This paper evaluates a policy to anticipate the load and configure the number of active servers so that a satisfactory quality of service is met, while reducing energy usage. Experiments are performed on a cluster prototype to validate the employed technique.
