Kurzfassung (in Englisch):

Cloud computing has many advantages which also governments and public authorities can benefit from. Therefore, a couple of European countries have already adopted cloud computing in the public sector or are planning to do so. In this paper, we evaluate eight European countries on their use of cloud computing in e-Government and compare them. As a result, the dominant cloud computing deployment model in those countries is a so-called G-Cloud (Governmental Cloud), a private or community cloud especially designed for national governmental use. In addition, no favored cloud service model has emerged, hence all standard cloud service models (Infrastructure, Platform, and Software as a Service) are adopted by most countries. Finally, half of the evaluated countries have anchored cloud computing in one of their national ICT strategies.
