Abstract
Recently, the outbreak of the COVID-19 crisis has led the educational organizations to move toward improving E-learning systems. These recommendations came with the rapid increase in virtualization technologies rapidly during the last years. The hybrid infrastructure of multi-cloud is needed for designing distributed systems, which enable mixing of various platforms. Improvements in cloud computing and containerized environments supply a charming chance to enhance the effectiveness and productivity for easy learning. Building Cloud Virtual Labs enable students connecting anytime and anywhere. These labs enable instructors to trace the students’ progress and manage the evaluation process. In this thesis, the performance analysis of building virtual labs and running six main educational services using docker swarm virtualization technology are explained in detail. The experimental results have shown that the maximum utilization of the central processing unit (CPU) has reached 13% for nodes, 11% for services, and 1% for container, which considered very efficient in terms of processing. Moreover, the results have proved the effectiveness of docker swarm in terms of memory usage since the maximum memory usage of nodes reached 101 MB, 103 MB for Container, and only 2MB for each service. Additionally, the maximum network transition has reached (941 Bps) for service.
