Energy Efficiency in Cloud Software Architectures

Cloud-based software is often considered as providing a greener, more energy-efficient solution. At the same time, it introduces more complexity and demands for new investments in cloud services, technologies, and competencies for migration, maintenance, and evolution of the underlying software architectures. To understand better the implications of cloud software architectures on energy efficiency, in this paper we present the preliminary results of a systematic literature review that investigates what kind of software architectures for cloud service provisioning allow to achieve energy-efficient solutions.
