Easy overlay networking in LXD with the Ubuntu Fan

The Ubuntu Fan is a great stateless overlay network solution built right into the Ubuntu kernel which LXD has offered for years now. It allows for very simple and reliable networking between systems in the cloud or locally.

It's automatically setup for LXD cluster users but can also be used with standalone LXD deployments as will be shown in this video.
