‘Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity network) over a network (typically the Internet)’. WikipediaBy 2015, the worldwide market for cloud products and services is estimated to reach between € 50 bn and € 80 bn. Cloud computing is a factor for change thanks to an increased efficiency of computer infrastructure utilization and standardized offers leading to lower costs. In order to ‘Unleash the Potential of Cloud Computing’ Europe gears up to tackle a series of challenges and the European Commission’s Communication on Cloud Computing released on 27 September 2012 identifies several key obstacles and corresponding actions: cutting through the jungle of standards, safe and fair contract terms and conditions and establishing a European Cloud Partnership to drive innovation and growth from the public sector.The EC Communication draws a lot of attention, comments and feedback from players involved in cloud computing, be they from industry, user community, governments, trade partners. This EIF debate will be an occasion to hear some of these reactions.
