Virtualization is the process of creating a software-based (or virtual) representation of physical technology. As an IT solution, this can apply to applications, servers, storage, and networks. It is the single most effective way to reduce IT expenses as multiple physical machines can be consolidated into fewer machines, allowing resources to be allocated more efficiently.
The less hardware there is, the less can go wrong.
In a virtualized environment, operating system software becomes less dependent on a specific piece of hardware, which allows for greater reliability for critical applications. The less hardware there is, the less can go wrong. This approach also creates an opportunity to save money by lowering power consumption, adding physical space to your office, and improving resource utilization.
