Abstract

With the onset of the corona pandemic and during periods of confinement, teaching has become totally online. E-Learning is successful for theoretical subjects, but this is not the case with practical workshops. The laboratories require a rather enormous hardware and software infrastructure. These resources consist of all the software, applications, computers components, servers, network and any element necessary for the implementation of the educational system and specially the practical work rooms (labs). The solution is to unify cloud computing with virtual labs and e-Learning. Cloud Computing represent a new digital technology for education that supports virtualization and offers the majority of computing resource as a pay-as-you-go service. The services offered by the cloud provide are mentioned in detail in a contract signed with user. The SLA contract (Service Level Agreement) contains a set of objectives (Service Level Objective) such as minimum downtime and penalties.

The adoption of Cloud computing for education is a solution for the problems of maintenance, security, insufficient hardware infrastructure and the unavailability of licensed and new software editions. This work is divided into two parts, the first is to show the usefulness of adopting cloud computing for teaching and especially virtual laboratories for practical sessions and on the other hand give an elastic model for the management of virtual laboratories in the goal of minimizing the cost by adapting the resources provided to the resources used while maintaining the quality of services. The established model is edited, analyzed, and verified by the CPN tools software.
