How it works...

As described before, there are several types of virtual platforms. I will explain the way one operates on VMware, which is one of the popular ones.

On every virtual platform, you configure hosts that are provided with the CPU and memory resources that virtual machines use and give virtual machines access to these resources.

In the next screenshot, you see a virtualization server with address 192.168.1.110, configured with four virtual machines: Account1, Account2, Term1, and Term2. These are the virtual servers, in this case, two servers for accounting and two terminal servers:

When you go to the configuration menu and choose Networking, as illustrated in the next screenshot, you see the vSwitch. On the left, you see the internal ports connected to the servers, and on the right, you see the external port.

In this example, we see the virtual servers Account1, Account2, Term1 and Term2; on the right, we see the physical port vmnic0.
