Cloud computing

Cloud computing, has its roots in late of 2007, but is becoming one of the next IT industry hot topics because it promotes the idea that users can move their data and applications to a remote “Cloud” and then they can have access in a simple and pervasive way.

This means that cloud computing  offers flexible dynamic IT infrastructures and configurable software services (Armbrust et al, 2009).
