Master's thesis

Cloud Computing is a powerful and flexible software environment, which delegates the material‘s management and in which users pay as they go. The migration of enterprise applications on the Cloud is increasing. Most of these applications are available as Web services that standardize access to business logic through Internet. However, the efficiency is not always complying with users’ needs. Constraints, such as threshold on response time, needs to be checked and assessed in order to avoid degradation and failure. As a result, the monitoring of the quality of service (QoS) is a key feature which allows satisfaction of the client needs. This paper objective is to experiment on the Cloud the AOP4CSM approach which monitors the QoS of Web services. In this work, (1) we conduct a survey on current Cloud providers and technologies, (2) we demonstrate the feasibility of AOP4CSM, (3) we experiment it on a large scale environment and test its robustness, then (4) we generate QoS reference values that can be used either for the analysis or the selection of Web services.
