The ASCETiC testbed - an energy efficient cloud computing environment

Abstract

Nowadays, the energy consumption of data centers is one of the biggest challenges in order to reduce operational expenditure (OPEX) and the carbon dioxide footprint. Most efforts are investigating the modernization of air conditions and server hardware, but also the optimization of resource allocations. Moreover, virtual server are migrated from one physical host to another in order to be able to shutdown unused physical computer nodes or even an entire rack. The Adapting Service lifeCycle towards EfficienT Clouds (ASCETiC) project tries to tackle this issue in another way. This project develops a toolbox that provides libraries and components which can be used to develop energy efficient cloud software on all three layers of the usual could stack. Thus, power consumption can be reduced by deploying energy efficient software in the cloud. This paper presents the innovative ASCETiC testbed located at the Technical University in Berlin (TUB), which is the deveopment and evaluation eviroment for the afore metioned software.
