I’ve used peerage (https://github.com/mrluc/peerage) on kubernetes for SD. It’s simple to set up and works in dev/test using its local adapters.

Libcluster looks good too. Everything bitwalker touches seems to be solid AF.

We're not doing anything special to help set up distributed Erlang at the moment. It would probably be difficult with App Engine because it's designed to manage stateless containers. But I could imagine setting up such a network with Kubernetes Engine, or definitely with Compute Engine VMs.

At elixir ATL meetup we setup an elixir app on GKE and connected the nodes via peerage in under 2 hours. Definitely possible!

How often do y’all meet up? I’m in Greenville SC but I could see a road trip happening periodically with the Upstate Elixir group.

It's once per month. https://www.meetup.com/atlantaelixir/

It's a pretty small group right now. I'm hoping that a new venue and push will help bring in more people.

I can't speak to GCP much, but gigalixir.com is a platform-as-a-service that takes advantage of Erlang's distributed network/nodes. I'm the founder.

It currently doesn't do automated clustering of nodes out of the box. It should be possible to build a clustering strategy for libcluster (https://github.com/bitwalker/libcluster) for App Engine. Note that there's already a kubernetes strategy which could run on the Google Kubernetes Engine.
