Oh, yeah...that is probably limiting. A quick scan seems to show Digital Ocean specifically drops multicast, and AWS/GCP/Azure have varying levels of "unsupported".

Would it work with Flannel/Calico, etc? Inefficient, but probably okay since it would be just service resolution.

Edit: Looks like no for Calico, Yes for recent Flannel, but Weave Works is probably a better choice, designed to support it from the start.

mDNS is only for local development. You can use a variety of tools such as Consul. Check out micro.mu for more info :)

Ahh. Might be a good update for the linked page.
