Napjaink informatikai vilgnak taln legkeresettebb hv szava a cloud computing, vagy magyar fordtsban, a szmtsi felh. A fordts forrsa az EU-s (Digitlis Menetrend magyar vltozata, 2010) A szmtsi felh zleti modelljnek rszletes lerst adja (Bgel, 2009). Bgel Gyrgy ismerteti az j, kzmszer informatikai szolgltats kialakulst s gazdasgi elnyeit, nagy jvt jsolva a szmtsi felhnek az zleti modellek versenyben. A szerz a szmtsi felh zleti elnyei mellett nagyobb hangslyt fektet dolgozatban a gyors elterjedst gtl tnyezkre, s arra, hogy mit jelentenek az elnyk s a htrnyok egy zleti, informatikai vagy megfelelsgi vezet szmra. Nem cskkentve a cloud modell gazdasgi jelentsgt, fontosnak tartja, hogy a problmkrl s a kockzatokrl is szljon. Kiemeli, hogy a kockzatokban klnsen a biztonsgi s adatvdelmi kockzatokban lnyeges klnbsgek vannak az Eurpai Gazdasgi Trsg s a vilg tbbi rsze, pl. az Amerikai Egyeslt llamok kztt. A cikkben rmutat ezekre a klnbsgekre, s az olvas magyarzatot kap arra is, hogy mirt vrhat a szmtsi felh lassabb terjedse Eurpban, mint a vilg ms rszein. Bemutatja az EU erfesztseit is a szmtsi felh eurpai terjedsnek elsegtsre, tekintettel a modell versenykpessget nvel hatsra. / === / One of the most popular concept of the recent web searches is cloud computing. Several authors present detailed description of the new service model and it's business benefits and cite the optimistic prognoses of the cloud experts regarding the competition of information system service models. The author analyses the operational benefits of the cloud application and give a detailed description of the inhibitors of the fast expansion of the service modell. He also analyses the pros and cons of the cloud for a business manager, an information and a compliance officer. When understanding the advantages of the cloud, it is equally important to review the problems and risks associated with the model. The paper gives a list of the expected cloud-specific risks. It also explains the differences in security and data protection approach between the European Economic Area and the rest of the world, including the USA. The explains why slower expansion of the cloud modell is expected in Europe than in the rest of the world. The efforts of the EU Committee in helping to spread the cloud model is also presented, as the EU's officers consider the model as an important element of competitiveness.

Nhny ve vonult be a kztudatba a cloud computing fogalom, mely ma mr a szakirodalomban s az informatikai alkalmazsokban is egyre nagyobb teret foglal el. Ez az j IT-technolgia a szmtsi felh szmtstechnikai szolgltatsaihoz kapcsold ERP-rendszerek szabvnyostst, elterjedst eredmnyezi. A szerzk cikkkben ttekintst adnak a cloud computing mai helyzetrl s a szmtsi felhben mkd adatfeldolgoz rendszerekkel (kiemelten ERP) kapcsolatos felhasznli elvrsokrl, illetve kezdeti, nmetorszgi alkalmazsi tapasztalatokrl. Kln trgyaljk az ERP-rendszerek j kivlasztsi cljait s kritriumait, melyek a felhkrnyezet specilis lehetsgei miatt alakultak ki. _____ The concept of Cloud as an IT notion emerged in the past years and proliferated within the business and IT professional community. The concept of cloud gained awareness both in the professional and scientific literature and in the practice of IT/IS world. The cloud has a profound impact on the Business Information Systems, especially on ERP systems. Indirectly, the cloud leads to a massive standardization on ERP systems and their services. In this paper, the authors provide a literature overview about the current situation of Cloud Computing and the requirements established by end-users against the other data processing facilities and systems, outstandingly the ERP systems. The majority of investigated cases are based on samples from Germany. Furthermore, the initial experiences of application are discussed. Separately, the recent selection objectives and criteria for ERP systems are investigated that came into existence because the appearance of Cloud in the IT environment.
