Visual quality estimation technique for services in cloud environments

Scientific problems, related to the interaction between IT-services suppliers and consumers in the cloud environments, has been described. The analysis of quality metrics, used for IT-services estimation, has been carried out taking into account the specificity of the cloud infrastructure that focuses on large-scale scientific problems solving. The technique, used for the visual express quality estimation of IT-services, has been proposed. The method of parallel coordinates has been used for multidimensional data visualization. The proposed technique can be used as an effective instrument for visual analysis of cloud services functioning (the dynamics of their quality indicators is considered).
