Virtualization technology is transforming today's IT community, offering new possibilities to improve the performance and efficiency of IT infrastructure by a dynamic mapping of the PC resources, enabling to run several applications and operating systems on a single physical system. Virtualization also offers elevated ease of use and error recovery solutions by encapsulating entire systems into single files that can be replicated and restored on any destination machine. This paper brings new elements related to the concept of virtualization, presenting the principles, the new architectures and the advantages of the virtualization. A new framework has drawn for using different types of operating system(OS) with a vApp in a single operating system. Creating the vApp's in VMware Studio and using the vApp anywhere any time.
