Management of large amounts of data on open systems
Safe management of data on “open” systems, in large quantities.
The infrastructures of Cloud Computing are large data centres that allow the user access to the necessary resources (application storage, programs, services).
In this way a new business model is born that allows one to noticeably reduces the internal IT power, to then be able to acquire it externally according to the needs at that moment.

is the most popular among companies, which, instead of installing the software that is purchased directly on their machines, they use a third-party company (Hosting Provider) which prepares the programs and then makes them accessible via the Internet.
(Platform as a Service)
it is very similar to SaaS in how it functions, but the distribution of the service is applicable to a software platform that is represented by a series of programmes, libraries and services.
(Infrastructure as a Service)
it is a process of virtualization of hardware structures outside the company (in fact it involves the use of remote hardware resources), to be used for applications in use.
