It has a research of a specialist who says that to each 18 months the power of processing of servers fold. is visible that the price of the hardware has diminished each time more. For that they are worried in diminishing the time of answers of the servers, this popularizao of the hardware price seems to be advantageous. The solution would be only to add serving to its datacenter and waiting compliments of the users. It seems logical, but this is not the reality.
Although this investment in servers is relatively low, it has a necessity of professionals to carry through the maintenance and the administration of the same ones. Each new server who is added in a net requires work price. This type of investment finishes very causing expense. Some prefer to solve this problem with consolidation of servers. The consolidation of servers consists of having a high machine with being able of processing. This machine starts to contain applicatory and the services that were being used in other servers. The problem of this solution is in the fact to have many environment conflicts of applications, this also finishes generating one high cost. The virtualizao of servers is the solution for this type of problem.
With the virtualizao it is possible to the same use some instances of Operational systems in the hardware. The Operational systems can be different. Each virtualizado server can have its specific applications. This simplifies the administration, it reduces costs, and it diminishes equipment number. He has some environments of virtualizao. The most known it is the VMWare, however its cost is high and alone it serves to the architecture x86, nor always this is enough. For who it desires something Free has the Xenserver. We are only at the beginning of this technology of virtualizao, some companies already are launching processing with potential for native virtualizao. With certainty the virtualizao is a technology that only comes growing.
