What is the virtualization of the operating system?

The operating system virtualization is a method of changing the standard operating system, so it can handle multiple users at the same time. These individual users would have no interaction between themselves. Their information would also remain separate, even if they use the same system. Although this technology has several uses, the most common use is in hosting situations and server consolidation.

with the virtualization of the operating system is set a single system to function as several individual systems. The virtualized system is set at the same time with the exception of commands from different users. These commands remain separate from each other; The results and the impact of any order have no effect on the commands from others. This source division should be transparent to users, it should not be able to determine whether they are in the virtual system or not.

An example of this process is the logout command. In a normal computer system, login the ZOPERATION SYSTEM Set the input to feedELE until it is required by the logout system or the user login back inwards. In the system using the operating system virtualization, when one user logs out of the operating system, only logs one user, but the rest of the users is not affected.

There are two common circumstances where the operating system, host environment and server consolidation are used. Site hosting companies, e-mail storage systems, and other account-based hosting systems often use virtual systems. Because users of these types of systems require very few resources, it is possible for many people to log in at once without taxation of the system. Each user works in his own environment without interacting with other users or seeing resources.

The second common area where the user can encounter the virtualization of the operating system is on the consolidated server. As a calculation of the systemias increased strength, one new server can be able to take the tasks of several older ones. In this case, it is possible to combine all server sources into a new computer. Because the old servers were separate, it is often necessary to maintain the insulation used by the original systems.

In both of these areas, more users who have no relation to each other must the same server. This is one of the most common aspects of the operating system virtualization. If users were part of the same group, they could exist and share resources. The only reason to keep it separate is when users have no relationship and have no reason to combine systems.
