Understanding Virtualization
We can’t assume that everyone knows and understands what virtualization is—we should perhaps assume the opposite.
Even though virtualization seems to be a ubiquitous technology, understanding what it does and how to manage it is still out of reach of many IT and Engineering managers.
Virtualization is essentially taking traditional hardware like servers and reducing the number of physical machines by converting most of them to virtual machines located within fewer of these physical devices. For example you could take 30 physical servers and reduce them to 5 physical servers that each have 6 virtual servers running inside them.
