Erlang is nice, but is outdated and does not handle clustering that well.

Erlang's distribution was always designed for redundancy and fault tolerance first, thus features like location transparency and heartbeats across nodes. There is no inherent service discovery mechanism built in (tools not solutions), and I suppose large topologies could benefit from third-party process registries.

I'd hardly call it "outdated", just that its default mechanisms for organization are a little different.
