The present study is focused on the social network analysis and its opportunities for identification and analysis of virtual social structures that emerge in the process of education. The social world and the relative position of the individual members and cliques within the social network is investigated and described, based on empirical data for online interactions (private messages and postings in course forums) between 901 actors (including 14 teachers, 2 administrators and 885 students) emerging in the learning environment of the elective course “Business communications in foreign language”. This can help in better understanding and managing of their behavior in the process of collaborative learning.

The global financial crisis set the modern companies several challenges associated with effective management and use of available resources and to optimize and reduce financial costs. Systems virtualization is one of the solutions that help to reduce the necessary equipment for an organization by optimizing use of existing hardware, combined with increasing fault tolerance of systems as well as easier maintenance and management of existing IT resources, which in turn reducing the incidental expenses of the organization for the maintenance of IT equipment. Project implementation in the Academy reduce the total number of supported physical servers, removing part of the accompanying infrastructure, reducing the cost of redundancy, maintenance, spare parts and consumed electric power, coupled with easier management, increased performance and increased fault tolerance.
