Review and Analysis of Cloud Computing Quality of Experience

Cloud computing is gaining growing interest from industry, organizations and the research community. The technology promises many advantages in terms of cost saving by allowing organizations and users to remotely gain access to a huge pool of data storage and processing power. However, migrating services to cloud computing introduce new challenges in performance and service quality. Quality of service (QoS) is and has been used as a means of monitoring cloud service performance. However, QoS is based on network parameters which do not necessarily reflect users’ quality of experience. This paper discusses cloud computing quality of experience as perceived by the person using the cloud-based applications and services. We also review a selected current contribution to the quality of experience (QoE). We have expert reviews undertaken to identify six key performance indicators (PKIs). Based on these six KPIs, we sent our surveys, collected feedback and analyze data to confirm that QoE measurement can meet organizational goals, user satisfaction and stakeholders’ requirements.
