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

Requirements for Cloud Services
• High bandwidth for fast virtual desktop applications
• Symmetric traffic demand instead of download only for uploading the content
• Managed delays for voice and video dependant collaboration applications
