New data management
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).
This is how a new business model is born, allowing one to noticeably reduce the internal IT power so that they are then able to acquire it externally according to their needs at that moment.
In the process of delivering cloud services, what stands out are
three different figures, each with different tasks:
Hosting Service Provider:
this is the provider of Cloud Computing services such as virtual servers, storage space, management applications;
this is the administrator of cloud services, regarding their use, configuration and supply, as well as being the go-between between Cloud Provider and Cloud Consumer;
this is the end-user, the one who uses the service that is provided by the Cloud Provider.
The public model of the distribution of cloud services includes three basic types:
The public model of the distribution of cloud services
provides three basic types:
Saas (Software as a Service):
this is the most popular among companies, those that, instead of installing the software that is purchased directly on their machines, use a third-party company (Hosting Provider) that prepares the programs and then makes them accessible via the Internet.
PaaS (Platform as a Service):
this 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.
IaaS (Infrastructure as a Service):
this is a process of virtualisation of Hardware structures outside the company (in fact, it involves the use of remote hardware resources), to be used for applications in use.
