This paper discusses the concept of Cloud Computing to achieve a complete deﬁnition of what a Cloud is, using the main characteristics typically associated with this paradigm in the literature. More than 20 deﬁnitions have been studied allowing for the extraction of a consensus deﬁnition as well as a minimum deﬁnition containing the essential characteristics. This paper pays much attention to the Grid paradigm, as it is often confused with Cloud technologies. We also describe the relationships and distinctions between the Grid and Cloud approaches.

Cloud Computing is associated with a new paradigm for the provision of computing infrastructure. This paradigm shifts the location of this infrastructure to the network to reduce the costs associated with the management of hardware and software resources . The Cloud is drawing the attention from the Information and Communication Technology (ICT) community, thanks to the appearance of a set of services with common characteristics, provided by important industry players. However, some of the existing technologies the Cloud concept draws on (such as virtualization, utility computing or distributed computing)... [continues]
