I will have to take the other side of that golden rule. Not sure where it came from. But when one has a decent handle on the tools at hand, they work wonderously well. I have bare metal servers tied together with L3 routing via Free Range Routing running BGP/VxLAN. It Just Works. No hard coded vlans between physical machines. Just point-point L3 links. Vlans are tortuous between machines as a Layer 2 protocol, given spanning tree and all of its slow to converge madness. Therefore a different Golden Rule: Always. Overlay. Your. Network. Leave a note if you'd like more details.
