Quality of service in cloud computing in higher education: A critical survey and innovative model

Cloud Computing, an emerging trend, in the e-learning sector has attracted number of service providers to the market in very less time, providing users with several applications at their disposal. However, while providing such service, not sufficient importance is given to the quality of the service, especially from the user's point of view. Hence it becomes necessary to monitor, track and quantify the QoS of the cloud computing e-learning applications in order to provide the right information to both the customers and the service providers. This information would help both the parties in terms of the comparison between the expectations and the capacity to meet them, but in this sector there is no standard model which defines the QoS parameters from the user's point of view. Thus, the need arises for developing a metrics model for enhancing the quality of service in cloud computing e-learning applications for higher education sector. In the current work, Quality of Service models are studied and comprehensive review of work done in this field is presented. Additionally an innovative QoS model for resolving this issue has been suggested.
