Meaning of cloud (what is it, concept and definition)

What is Cloud:

Cloud 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 cloud computing is used. The service is also known as cloud computing, cloud computing, or cloud service.

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

• Store information without the need to carry a storage device, such as a pentdrive , access user information anytime, anywhere ; make online backups or backup , access the software without downloading 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: the public cloud, the private cloud, and the hybrid cloud.

It is known from public cloud to cloud services provided by suppliers to all types of users, individuals or business, who do not have their own networks of servers. Among the 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 stored information.

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

Disadvantages of the cloud

Although cloud services solve the problem of data accessibility anytime, anywhere by accessing the Internet, it represents a security problem.

The problem is that the user delegates control and protection of their personal or business information to the service provider. Two disadvantages follow from this:

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

Added to this is the fact that cloud services, as designed to date, make the user dependent on the provider. This means that they undermine your freedom by putting 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.
