Virtualization – cloud's best friend

One of the very simple and best-known features of virtualization is that it allows us to run multiple operating systems together on a single hardware.

So, essentially, we can run Windows and Linux together simultaneously in a single box without having to worry about much.

I still remember my senior saying that I was very lucky to be born in the days of virtualization as earlier if they messed up their system during testing, they had to spend 2-3 hours re-creating it, while in virtualization, once the snapshot is taken, it takes just 2 minutes to go back to its original state. The snapshot and restore features have been one of the most preferred and useful features, specifically when doing testing related to compiling kernel.
