Cloud Computing and Big Data are the current hot topics in research and industry. Based on the enormous amount of preliminary work, ranging from grid and distributed computing to data mining and clustering, to name only a few approaches, cloud computing has become a defacto standard for computing in general and data-intensive industry tasks in particular. Thus, a lot of questions about how to d...

In the literature, Cloud computing is seen as an evolution of Grid computing, which itself is an evolution of distributed computing and supercomputing. The distinction between the Grid and Cloud concepts is not clearly defined, both of them referring to an externalization of the private data centres. Two main advantages are expected from these two approaches. Instead of investing in the install...

Cloud Computing is drawing people’s attention from all walks of the IT world. It promises significant reduction of cost among many other advantages as it proclaims, including increased availability, fast provision, ondemand, and pay-per-use, etc. This paper presents a novel model of Cloud Computing, named “Credit Union” model (referred to as the CU model or CUM for short). This model is motivat...

According to Makhlouf & al (2016), to survive the multidimensional changes in markets related to frequent evolution of national and international regulations, consumers’ behavior, information and communications technologies (ICT) and the globalization phenomenon, companies have constantly to reinvent themselves. They seek to transform their information systems in order to integrate quickly the ...
