Open Stack

There is no right or wrong way. The reason its broken out onto a bunch of network devices during documentation is to make things easier to understand. You can run the entire service stack from a single nic single ip.

You can also run your tunnels over the same nic and on the same VLAN you use to access your internal APIs if it's a small cloud and you're not concerned about bandwidth bottlenecks. This also allows you to have a single nic on your computes. I do this for dev clusters when I've had to go dumpster diving for hardware.

As long as you manage to keep your networks separate(d) using VLANs or something, NIC use is kind of irrelevant as far as requirements go.

Is it compulsory to use Three NIC for the network node while forming the cloud on physical machine.
