The improvement of communication and the exchange of teaching resources between teachers and students has developed a model of web services based on cloud computing technology. Today's models and systems (in the application approach) are used according to the user's needs, while the rest of the time computing resources remain not used. Such services are characterized by extremely high level of security and synchronization of files that are continuously exchanged. The infrastructure that is based on cloud technology provides uninterrupted simultaneous work of great number of different virtual machines on which are installed different systems and application software. For the purposes of the experiment, teaching resources are offered in the form of a virtual machine. Experiment included approximately 500 respondents in the territory of the Republic of Croatia and Bosnia and Herzegovina. The experiment results show that the system for e-learning (online education) developed in cloud environment is more scalable and shows better performance from the currently used classical server oriented system.
