Network Virtualization

The evolution of the processing power of today's computers is notorious in recent years. Unfortunately, a large part of this power is not actually used in everyday life, and there is therefore a growing concern about the waste resulting from this underuse. Technologies such as virtualization, in the first place, and Cloud Computing, as the most advanced stage of this, are ways to reduce such waste.

The real is understood as something with physical characteristics, concrete, tangible and the virtual associated with something simulated, abstract, an imitation of the real. This is where virtualization fits, the simulation of a real environment that supports an entire environment that goes from the operating system to the applications without the need for access to the real machine, which in this case acts as host of this technology.

Virtualization fits into an illusory world of several virtual machines (VMs) independent and isolated from each other, each with its own operating system (OS) and potentially different from the OS of the others.
