Background: In recent years, cloud computing has grown vastly. Cloud computing represents a new model for IT service delivery and it typically provides over-a-network, ondemand, self-service access, which is dynamically scalable and elastic, using pools of often virtualized resources. However, this new paradigm is facing diverse challenges from many fronts. Methods: We conducted a systematic literature review of potential challenges of cloud computing. Documents that described challenges of cloud computing were collected of routinely. We grouped identified challenges in taxonomy for a focused international dialogue on solutions. Results: Twenty-three potential challenges were identified and classified in three categories: policy and organizational, technical and legal. The first three categories are deeply rooted in well-known challenges of cloud computing. Conclusions: The simultaneous effect of multiple interacting challenges ranging from technical to intangible issues has greatly complicated advances in cloud computing adoption. A systematic framework of challenges of cloud computing will be essential to accelerate the use of this technology for working well in fact and in order to face with respect to mitigating IT-related cloud computing risks.

Following the suspension of classes in Morocco due to the health crisis related to COVID-19, an adaptation of the pedagogical intervention of teaching is required. Distance learning is an essential lever contributing to ensuring the educational continuity of students. In this sense, our contribution is to ensure the educational continuity of students during the period of containment through the use of a digital manual. The digital textbook is made available to students of the 1st year of the qualifying secondary education. Through a tracking grid, we measured the student engagement during two different periods without and with the use of the digital textbook. The results show that the digital textbook was able to elicit student engagement in the completion of learning activities with a remarkable improvement of 57.1% in student engagement rate over the two periods (t (273) = 11.059, p < 0.001). Student engagement while using a digital textbook can lead to better academic performance (r = 0.743, p = 0.000 < 0.01). No one can deny the importance of distance learning as a powerful tool that allows teachers to improve their professional practices in the presence of solid, quality instruction in the classroom that promotes the acquisition of skills and the development of competencies in students.
