What is Cloud:

The Cloud in computing refers to acomputing service that processes and stores data through a network of servers . The term comes from English, in which the expression cloud computingis used . The service is also known as cloud computing, cloud computing or cloud service.

This type of services can be free or paid through a subscription. Among the many uses it has, the cloud is particularly useful for:

  • Store information without needing to carry a storage device, such as a pentdrive ;
  • access user information at any time and place ;
  • back up or backup online;
  • access the software without downloading applications;
  • improve the performance of the local computer by decreasing the volume of data stored in it;

Types of cloud

Cloud services are divided into different types: the public cloud, the private cloud and the hybrid cloud.

It is known as cloud public cloud services provided by providers to all types of users, individuals or businesses, who do not have their own server networks.Among public cloud providers we can mention Google Drive, DropBox,

The private cloud is managed by the same organization that uses it, so there is a greater guarantee of security and privacy of the information stored.

The hybrid cloud results from the combination of the public cloud with the private cloud. A certain company, owner of the cloud, shares some sections of the cloud in a controlled manner.

Disadvantages of the cloud

Although the cloud services solve the problem of accessibility of the data at any time and place through Internet access, it represents a security problem.

The problem is that the user delegates the control and protection of their personal or business information to the service provider. From here there are two disadvantages:

  1. There is no infallible service, therefore, eventually some part of the information may be lost or modified.
  2. Since the control does not reside in the user, the privacy of the account can be easily violated by personnel of the service provider, which represents a security risk for the user.

This is compounded by the fact that cloud services, as they are designed to date, make the user dependent on the provider. This means that they undermine their freedom by placing limitations on the number and type of applications that this may require. The user of the cloud can only use those applications that the cloud provider designs and allows.
