Services can be made energy-aware by annotating them with information regarding energy consumption associated to their structure, execution platform, and organizational and strategic issues related to their development, deployment, and maintenance. This information is characterized in this paper in terms of Green Performance Indicators (GPIs) annotating a service in terms of the IT resources they use and also of development costs, human resource, or environment impact the service has. A service analysis approach is proposed based on monitoring the proposed GPIs, to enable the analysis of services from their energy consumption point of view. Such an approach allows estimating energy efficiency of services performing the same function, but with different energy consumption characteristics, by supporting a comparison of behaviorally similar services (e.g., an on-line purchasing service) through the analysis of their GPIs. By collecting details from GPIs of services, we propose a model for an energy certificate, called Green Certificate, aimed at classifying services as more or less efficient in terms of the energy they consume during their lifecycle.

Abstract
Services can be made energy-aware by annotating them with information regarding energy consumption associated to their structure, execution platform, and organizational and strategic issues related to their development, deployment, and maintenance. This information is characterized in this paper in terms of Green Performance Indicators (GPIs) annotating a service in terms of the IT resources they use and also of development costs, human resource, or environment impact the service has. A service analysis approach is proposed based on monitoring the proposed GPIs, to enable the analysis of services from their energy consumption point of view. Such an approach allows estimating energy efficiency of services performing the same function, but with different energy consumption characteristics, by supporting a comparison of behaviorally similar services (e.g., an on-line purchasing service) through the analysis of their GPIs. By collecting details from GPIs of services, we propose a model for an energy certificate, called Green Certificate, aimed at classifying services as more or less efficient in terms of the energy they consume during their lifecycle.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
