ABSTRACT
The advantages of this new computational paradigm with respect to other competing technologies are clear. First, cloud application providers strive to provide the same or better services and performance as if the software programs were installed locally on end-user computers, so the users do not need to spend money buying complete hardware equipment for the software to be used. Second, this type of environment for data storage and computing schemes allows companies to get their applications up and running faster, with a lower requirement of maintenance of the IT department since it automatically manages the business demand by dynamically assigning IT resources.
