Today, "virtualization" is a very common term in the software deployment and IT worlds. Most companies are leveraging this technology not only to deploy their applications, but the virtualized images are also being used by the IT department to provide a new system to a new employee in the organization.
Virtualization had made IT infrastructure provisioning very fast, quickly reproducible, and reliable. It has also made debugging, troubleshooting, and the availability of operational infrastructure much better.
