A Comparative Analysis of Multicriteria Approaches for Cloud Services Selection
Carlos Eduardo da Silva, Luciano Ferreira, Escola de Ciência · 2013
With the visibility that cloud computing has been acquiring, it is observed that the provision of computational resources as services is growing increasingly, leading to a large number of services being offered. These services have heterogeneous managerial and technical specifications, so that organizations wishing to use such services need mechanisms to assist in the decision making process to choose one that best suits their needs. This paper addresses the issue of selection of cloud services based on the analysis and use of methods, models and algorithms for selection which meet multiple criteria. We present an unified approach for specifying user objectives, capturing properties of available services, and applying a selection method. Our approach is evaluated by combining two multi-criteria methods for selecting real cloud computing services.
