Eureka! Institutional Repository

The task of this thesis is the development and creation of a cloud computing system, whose purpose is to share Operating System (OS) images to students of the department of Informatics at the Alexandrian Technological Educational Institute of Thessaloniki. The development of such an environment can have many applications which would ease the educational experience not only for students and personnel but also for the institute as a whole. More specifically students can benefit from this system, by being enabled to have a personalized operating environment, at any point during the day, be it in the premises of the Institute, or through the use of a VPN. Institute personnel, can create separate OS images with the programs and services they desire, significantly improving the subject matter of each class. In addition the capacity of the computer labs would be increased, since it would be independent of the number of personal computers. Finally, the CCS we created can be connected to, through the means of a simple browser. The user of this software, can create and distribute images through the network, or use other tools, creating a complete cloud computing experience. We used the Openstack open source cloud software, and our OS was based on Linux; particularly on Ubuntu Server distribution. Finally, we used the HTTP and SSH protocols. HTTP was used in order to connect with the Web Interface of the system and the SSH protocol in order to have access not only to the command line of the bare OS but also to communicate with the images CLI.
