Clustering in Elixir 1.9 with Mix Releases and libcluster
We just published a guide to automatic clustering in Elixir 1.9, with Mix releases and libcluster.
The cluster automatically discovers nodes as they join or leave, allowing you to scale by simply increasing the number of instances for your app. The source code is available at GitHub - render-examples/elixir_cluster: Distributed Elixir Cluster on Render with libcluster and Mix Releases · GitHub.

No, it becomes valuable as soon as you have >1 instances for high availability. For example Phoenix channel broadcast and Phoenix presence will use clustering
for communicating between nodes.
