Thanks for the rich reply. So you mention PaaS may not be suited for persistent processes. Do you think it could work well with Phoenix’s channels (web sockets)? As I understand, they create a process per user web socket connection. Phoenix also allows multiple nodes to discover and share these channels’ state AFAIK — are there any tools that make this discovery easier from Google’s side for Elixir to automatically connect the nodes, say when instances are brought up or down? I think it would be good to have this as part of the documentation if there is, as it would be a key selling point if it’s relatively easy.
