Pretty cool demonstration of Weave[1]. Is it correct to summarize Weave as "Hamachi for Docker containers"? For those that don't remember Hamachi, perhaps "VPN for Docker containers" is a more contemporary technical description.

EDIT: I know this was just a proof-of-concept, but I believe if one were to bring up a multi-datacenter Cassandra ring, you'll want to ensure your replication configuration is "NetworkTopologyStrategy" and not the default "SimpleStrategy" setting[2].

I think VPN is a use case for SDN. Weave is fundamentally a software network that provides a virtual switch at layer 2.
