Measuring energy consumption for web service product configuration

Because of the economies of scale that Cloud provides, there is great interest in hosting web services on the Cloud. Web services are created from components such as Database Management Systems and HTTP servers. There is a wide variety of components that can be used to configure a web service. The choice of components influences the performance and energy consumption. Most current research in the web service technologies focuses on system performance, and only small number of researchers give attention to energy consumption. In this paper, we propose a method to select the web service configurations which reduce energy consumption. Our method has capabilities to manage feature configuration and predict energy consumption of web service systems. To validate, we developed a technique to measure energy consumption of several web service configurations running in a Virtualized environment. Our approach allows Cloud companies to provide choices of web service technology that consumes less energy.
