Virtual laboratories are fully interactive simulations in which students conduct experiments, collect data and answer questions to assess their understanding. The primary objective of virtual cloud-based lab solutions is to provide customized IT environments for users. In today's information, networks and security training, time and location are one of the crucial elements for participants. Many universities and organizations have already taken some advancements by providing online training and labs that are accessible from anywhere in the world. In this paper, we conduct a small-scale trial of VCL solution to support higher education in networks and security courses of some hard concept such as the security or networks tests and experimentations. We describe and analyze in more detail the performance of this solution using load testing.
