In view of the actuality use of cloud computing we have in the context of diploma thesis developed e-course for a guided education for building clouds based on OpenStack platform. In the first part we set design and content structure of the e-course on basics of a psychological approach of learning and guidelines for making e-learning. The course was divided into theoretical and practical learning units. Within the theoretical units were presented cloud computing, virtualization and the functioning of the platform. Within the practical part of the course we performed a basic installation and setup of platform. After the execution of the course, we have made empirical part of the thesis which elaborated evaluation of the course. We have performed a study on a small group of students who have made a systematic assessment of its value and some improvements in the future. In general the score of course is good. All activites of the course were performed in Moodle virtual classroom.
