Types of cloud

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:
- There is no infallible service, therefore, eventually some part of the information may be lost or modified.
- 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.
