- One of the big paradigm shifts
that we're seeing in networks today,
is the move towards virtualization.
For example, instead of having different physical servers
each running their own operating system,
we can have one physical server.
And on that one physical server we could run
virtualized instances of maybe
a couple of Microsoft Windows servers,
a couple of Linux servers, all on one physical server.
That can give us tremendous cost savings.
And in this module, we're going to talk about virtualization
beyond just server virtualization.
We're going to see that we can virtualize network devices,
we can virtualize data paths,
we can virtualize a network itself.
Now join me in our first lesson as we take a look
at how we can virtualize different types of network devices.
