Setting up closed environments and upgrading them is a process independent of any physical hardware, which makes the entire process a lot more convenient. The costs involved are significantly lower and there are no space requirements. Maintenance of virtualized environments can be relatively easier due to no involvement of actual hardware, and that significantly increases the up-time of data centers and servers operating in virtual deployment scenarios. Portability is also extremely convenient and easy. Virtualization is most ideal and suitable when deploying and implementing a system across multiple users on a large scale.
