Today, the daily operation of companies is unimaginable without servers. The problem core of the problem is that several server application needs to run simultaniously, so multiple computers are operating in parallel. The average utilization of these server computers is very low, so their operation is uneconomical. The essence of server virtualization is that on one phisical machine we run several virtual servers , so from the outside they can be seen as separated machines. This is an energy-saving and devices friendly solution, which can reduce operating costs, but it is possible to maintain the load level consistently high.
-
The physical server server utilization can be increased from 10-20% to 85-90%.
-
The hardware cost, the hosting costs and the energy consumption can be radically reduced.
-
The security can be increased by the separation of the functional elements.
-
Easier management - one "click" to create a new server.
-
Its possible to dynamicly assign resources (memory, storage, network bandwidth, CPU time) to the servers and applications with variable functions, so increased availability can be guaranteed.
-
It is also possible to run a variety of operating systems on the same physical device.
