Server virtualization is used to mask server resources from server users, sharing in a secure and reliable way hardware resources between the various virtual environments that exist on it.
Regardless of the diversity and complexity of the company’s information system, virtualization brings a whole host of advantages. The most obvious advantage is the process of system consolidation and the controlled growth of the number of servers in the information system.
Consolidating the system achieves significant financial advantages. Today’s x86 systems have an average percentage of the utilization of available resources (processors, working memory, and data storage systems) at a level of 10-15%, which says enough about the utilization of current resources that the user possesses.
Quality consolidation brings an increase in the utilization of available resources of 50-85%. When we transfer this to actual systems, virtualization realistically reduces the number of servers required in the system by a minimum of 3 to 5 times.
