The Migration of the University IT Infrastructure toward a Secure IaaS Cloud

The appealing features of Cloud computing have been fueling its integration in many sectors; economy, industry and education. Thus, it become widely used for personal services and for entertainment. Since the arrivals of this paradigm and the providing of services through Internet, information technology live a radical shift in its adoption. The financial benefits and the informatics features of Cloud Computing makes it a necessity to maintain the development of many sectors, as well as education. However, its security weaknesses are the major barrier for its adoption. Over the years, the IT and financial needs of the university keep speedily growing with the increasing number of students. To overcome its requirements, university is called to adopt the Cloud Computing technologies. We propose in this paper a design of a private IaaS Cloud adopted for the university IT infrastructure. Also we propose two solutions to improve its security; especially the isolation of data in the IaaS Cloud, and the isolation of networks within the university by adopting the Tree-Rule Firewall approach.
