Docker Overlay Network
The overlay driver builds one virtual network across multiple Docker hosts by giving each host a VXLAN tunnel endpoint and distributing the IP-to-host mapping through Swarm's control plane, so containers on different machines communicate as if on one bridge. Embedded DNS and virtual-IP load balancing ride on top for multi-host service discovery.
This Concept is waiting for its first lesson!
