This research aims to highlight the main challenges and concerns of using Cloud Computing (CC), not only focusing on the benefits. The research presents a systematic review of CC concepts, models, services, and their positive effect and significant impact on higher education institutions. The result of the conducted analysis found many challenges and concerns that have to be overcome before deciding to adopt the CC in the Higher education environment.Transition to the CC model must be done according to a comprehensive plan that handles the different challenges. Concerns and challenges are classified, and each subcategory is discussed. The guidelines and recommendations offered by this research can help to overcome many challenges and clarify the roadmap of successful adoption of CC in high education institutions.
