Virtual cloud network laboratory based on IaaS with automatized creation of network topology on demand

The article describes an approach to create virtual cloud network laboratory. The topology is created with the visual editor. Then a script for network deployment is created. It is based on the scheme description. For implementation of this approach the cloud system based on OpenNebula has been created. The experiment has shown the efficiency of using cloud systems in IT education. Even the small cloud datacenter has provided virtual classes for studying operating systems, network administration, cloud services and creating various cloud services and networks.
