Abstract

The continuous increase in electrical and computational power in data centers has been driving many research approaches under the Green IT main theme. However, most of this research focuses on reducing energy consumption considering hardware components and data center building features, like servers distribution and cooling flow. On the contrary, this paper points out that energy consumption is also a service quality problem, and presents an energy-aware design approach for building service-based applications. To this effect, techniques are provided to measure service costs combining Quality of Service (QoS) requirements and Green Performance Indicators (GPI) in order to obtain a better tradeoff between energy efficiency and performance for each user.
