Virtualization & Cloud


·   Virtualization


Virtualization technology actually started in 1960 by logically allocating the resources of mainframe to different applications. After over a half century of development, the meaning of this term is extended and generalized in IT and applied to many kinds of resources including hardware, operating system, storage and network.    

In general, virtualization reduces the limitation of the whole datacenter and the equipment itself, it enhances the performance and efficiency of products and eases the complexity of integration, the infrastructure is converged and standardized, the cost of investment and operation is reduced.
