Today, virtualizao of servers is one of the subjects in high in the technology. But after all which the benefits of this technology? It has little time behind the applications were of the type customer-server. In this standard it had the necessity to have a customer installed in desktop that thus it was connected to a data base. Thus a server for an application was necessary. With passing of the time, he had a popularizao of the Internet. This made with that great part of that they use applications desktop started to use applications web.
Therefore, applications web are accessible of any place, its updates are less custosas. However this brought a significant increase in the number of servers. The type of preponderant architecture will be the guided architecture the services (IT SOUNDS), this consists of adding layers in applications. If it will not have virtualizao, layers mean more serving, more serving mean increase of costs, management, consumption of electric energy, without counting complexibilizao of environment that is cabeamento and backups. The power of processing of the servers grows each time more, this if it becomes clearer with the technology multi-Core.
The servers with great potential of processing and distributed applications mean high performance, but this high performance always requires bigger costs. In the question electric energy, the efficiency is each lesser time, for the fact of the processing to be each more powerful time. It is specified that only about 10% of the processing the day is used in a server x86 in the day. The virtualizao if popularizes as great solution for these problems. Virtualizao nothing more is that the possibility to create virtual machines sharing of the same equipment of the hardware. It is possible to create serving distinct, for distinct tasks in the same the hardware. Thus we obtain exempting in them of the risks of conflicts that the consolidation of servers could bring. When using the virtualizao, is possible to the same place certain number of servers virtualizados in the hardware of a physical server. This increases the efficiency of these equipment in what it refers to the energy. This brings enormous benefits for a company.
