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. -Erik On Dec 27, 2015 11:28 PM, "Adam Lawson" < alaw...@aqorn.com > wrote: 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.
