What is the Cloud

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

These types of services can be free or paid for through a subscription. Among its many uses, the cloud is particularly useful for:

Store information without having to carry a storage device, such as a pen drive;access user information anytime, anywhere;
make backup copies or backup online; access the software without having to download applications; improve the performance of the local computer by reducing the volume of data stored on it;

Cloud types

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

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

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

The hybrid cloud It 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 cloud services solve the problem of data accessibility 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. Two disadvantages arise from this:

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

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