Generic Usability Monitoring Model for Cloud Computing Environment (GUM)

The paper proposed a new generic model to monitor the quality of the service parameter in the cloud computing environments. Usability requirement is a main factor to enumeration the quality of any software system, where the user satisfaction is the principal factor that gives a perception of the software system success or failure. Most of the existing cloud computing environments are very complex and not easy to use, as a result of that the authors start developing methods and mechanisms to evaluate if the cloud computing environment usable or not. Several papers clarify these methods, according to the author opinion. In this paper we focus in term of usability based on Three-Dimensional (3D) approach as a one of the usability evaluation methods. This research proposed a new model that helps the third party to monitoring the usability of the cloud computing environments, and gives the result to the costumers. Our model aims to use different usability evaluation methods such as: design principles, user satisfaction, the process of inspection, and user participation (testing & questionnaire) to determine the usability of this environment type. The Three-Dimensional (3D) approach is a proposed usability evaluation method that designed to pass the cloud computing environment in three phases during the evaluation process. Where there will be a certain degree of each stage. The first two phase's represents 40%, while the last one represents 20 % due to its importance, the total of the three phases are 100 %. Therefore, that will represent the percentage of the usability of the cloud computing environments.
