User-Friendly Visualization of Cloud Quality

Abstract

The cloud computing paradigm is one of the most promising of its kind. The demand and supply of online delivered software have been continuously growing. However, reports have shown that various Software as a service solutions have not succeeded in reaching cloud user expectations. Hence, users need to be satisfied with the service quality which is determined by the fulfillment of both functional and non-functional requirements. Currently, the evaluation of the cloud service quality consider-ing individual requirements is up to the user. Unfortunately, the amount of non-functional quality criteria is very high and some are laborious to determine. We believe that an information system could support and enable users without specific knowledge to evaluate comprehensively and rapidly the quality of their cloud. In this paper we first present a quality model for SaaS. In addition, we demonstrate how the quality information should be structured and visualized in a user-friendly way. With the provided transparency users are able to establish quality awareness in the long term.
