There is perhaps nothing more used, yet less well known than the Cloud. We need to start by asking ourselves this question: if we need to do a job, but we don’t have the right tools available to do it, what can we do? If we don’t want to buy the tools, we can rent them.

That is the explanation of cloud computing, using the resources, for example storage space and calculation power, of a network of computers belonging to someone else that offers them through Internet. As long as a device has access to the web, it has access to the data and software of these servers.

Cloud computing is a popular option for many different reasons: it can guarantee cost saving, higher speed and effectiveness, better performance and data security. For companies the advantage can mean virtually infinite horizontal on-demand scalability which allows them to offer digital services that can function and elaborate the data of one user just as easily as hundreds of thousands.
