We run a significant amount of stuff on spot-instances (AKS nodes) and use the service detect, monitor and gracefully handle the imminent shutdown on the Kubernetes side.
Could you elaborate why mnesia is useless? I've only used erlang and elixir in hobbyist projects but in theory mnesia felt like great fit into the erlang ecosystem.
thanks for your answer so basically it relies on plain TCP and its reliability features. If you need something more sophisticated you gotta do it yourself within the application code (or using libs).
