There are many very costly and high configuration systems currently on the market for hosting servers with different purposes. These environments are IT infrastructures frequently deployed in large database center servers. But these high configuration system never utilized there full resources .Moreover, for increasing the number of user and assets in the market we focus on the resources and its optimization by costing, space and performance of physical machines. For achieving, there is a critical need to evaluate performance of large database centers in virtual environments. Virtualization not only help to utilize wastage resources even it saving space, resources and costing of hardware’s on same execution timing as on separate physical system. For this, make database server on one separate physical machine and another one in the virtual machine which shows the execution timing in both the case are same but virtualization saving space, hardware’s, costing and utilize free resources of base system of virtual machine.

Keywords : Virtual Machine, performance, experimentation, database, cost comparisons.
