6. Definition: As a service model for computing services based on a set of computing resources that can be accessed in a flexible, elastic, on-demand way with low management effort Based on OECD August 2014 publishing: Lowers the entry barriers for new entrants in multiple sectors Small Medium Enterprises save on investment costs and at the same time, benefit from gaining access to cutting edge technology and services, including software updates Due to economies of scale and possibility to aggregate the demand of multiple users of cloud computing, especially public clouds, providers have much lower operating costs than companies would have if they would run their own IT infrastructure Cloud computing increases GDP 0.05% in the short run(1 year adoption) and 0.3% in the long run(5 year adoption). This GDP growth is further expected to have direct and significant counterparts in the effects of employment and n the creation of SMEs. In case carbon intensive energy used, total annual carbon abatement potential of 7.42Mt CO2e which represents about 4% of the current carbon footpring of the ICT sector in European union or about the permanent removal of nearly 2.5M cars. Upload speeds will become a determinant factor for the use of cloud computing services
