	abstract = {<p>Following the as-a-service philosophy, a cloud service provider offers computing utilities in the form of virtual resources instantiated on top of a physical infrastructure. In order to meet business requirements still providing high-quality services, performance evaluation needs to be carefully carried out with the aim of optimizing data center utilization and increasing user satisfaction. In this context, power efficiency plays a critical role pushing service providers towards the application of innovative green strategies. In this paper, we present an analytical framework, based on stochastic reward nets, that allows to evaluate different resource allocation policies in a green cloud. A use case is shown in order to illustrate the approach, modeling scattering and saturation allocation policies and comparing them to a purely physical data center scenario. A validation of the proposed model against the CloudSim framework is presented and several numerical results are provided, demonstrating the effectiveness of the approach as a powerful tool for a cloud service provider to perform well-informed decisions about theresource allocation policies to be enforced. {\textcopyright} 1990-2012 IEEE.</p>

	abstract = {<p>The right setup of a testbed is important for enabling the rapid development and deployment of cloud services, in particular all the times the testbed hosts more concurrent interactions. This work shows how to configure an environment where more developers insist on it. In particular what tools are indispensable for managing compelling distributed cloud environments. We looked at mature Open Source solutions, performing their smoothed integration. The paper describes all parts necessary for accomplishing complex scenarios, even in a bounded perimeter as the VISION Cloud EU project offering. VISION Cloud represents the reference architecture dealing with Cloud Storage, and our work attempts to provide solutions applied on VISION, but suitable for any type of framework. {\textcopyright} 2012 IEEE.</p>
