The monitoring of QoS parameters in services Computing as well as in Clouds has been a functionality provided by all contemporary systems. As the optimization of energy consumption becomes a major concern for system designers and administrators, it can be considered as another QoS metric to be monitored. In this paper, we present a service framework that allows us to monitor the energy consumption of a Cloud infrastructure, calculate its energy efficiency, and evaluate the gathered data in order to put in place an effective virtual machine (VM) management. In that context, a simulation scenario of an eco-driven VM placement policy resulted in a 14% improvement of the infrastructure's energy efficiency. In total, the proposed approaches and implementations have been validated against a testbed, producing very promising results regarding the prospect of energy efficiency as an important quality factor in Clouds.

Clustering Web services that groups together services with similar functionalities helps improve both the accuracy and efficiency of the Web service search engines. An important limitation of existing Web service clustering approaches is that they solely focus on utilizing WSDL (Web service Description Language) documents. There has been a recent trend of using user-contributed tagging data to improve the performance of service clustering. Nonetheless, these approaches fail to completely leverage the information carried by the tagging data and hence only trivially improve the clustering performance. In this paper, we propose a novel approach that seamlessly integrates tagging data and WSDL documents through augmented Latent Dirichlet Allocation (LDA). We also develop three strategies to preprocess tagging data before being integrated into the LDA framework for clustering. Comprehensive experiments based on real data and the implementation of a Web service search engine demonstrate the effectiveness of the proposed LDA-based service clustering approach.
