Virtual Private Server (VPSs)

To practical effects a virtual servant is similar to a dedicated servant. The virtual servants lodge in a physical servant, so that in a same physical servant several virtual servants lodge who operate as if dedicated servants they were. Each Virtual Servant is separated completely concerning software although he shares the same machine and its resources with the rest of virtual servants. That is to say, the disc space, the memory and the processor distribute (they do not share) between the number of virtual servants as well as software since each virtual servant is an independent servant as much in the operating system as in installed software.

Each Virtual Servant has reserved his disc resources, memory and processor, in this way if one of the formed virtual servants in the same machine exceeds its reserved resources, its virtual servant will not be affected.

Advantages of the use of virtual servants

The virtual servants offer a greater control on the resources of the servant on who he is formed. This fact allows us to exclusively add own functionalities to each virtual servant, applications, to reinitiate it, etc. without the rest of virtual servants is affected. In addition thanks to the administrative panels it will be able to much more do this and through interfaces of control Web from any place with a connection to Internet.

Another one of the great advantages is the referring one to backups since backups of sisitema can be realized “completely�, not only of files and the information lodged in the servant but backups of all the configuration of the servant and all this of fast and comfortable way that will, among other things, allow to change its virtual servant him of a physical servant to another one in very just a short time and of comfortable and simple way.

Other remarkable advantages of the virtual servants:

• Resource management: you will be able to assign and to reasignar the resources (CPU, disc, network, memory, etc.) of the virtual servants in real time and of comfortable and simple way.
• Global administration: When being in a same physical servant, you will be able to manage with a same tool global changes that affect to all the lodged virtual servants in the machine.
• Maxima availability: To the power to transfer of fast form all the virtual servants of a physical machine to another one at the time of carrying out maintenance tasks, repair or extension of the physical servant.
• Scalability: It increases the number of virtual servants in real time distributing the resources free of the system to increase the number of lodged virtual servants.

Advantages against the shared lodging

In the case of the lodging shared Web all dominions lodged in a same machine usually share as much resources as the software of the system. This situation can give like result that by a failure in another dominion different from his, its page Web stops being visible or stops working correctly.

In the case of the lodging shared Web all the dominions share the rest of applications and services like for example the mail servant. Therefore it is much more dangerous surroundings since by a bad operation in one of the dominions it would be possible even to be seen affected all the physical servant getting to produce a global refusal of services in all the dominions shared lodged in the same machine.

A virtual servant offers a greater robustness and guarantee on watch since he makes sure that no other user can monopolize his resources.
