nerves VS libcluster

The nerves package's README.md explains what each repository is responsible for with a comprehensive listing.

You may be already aware of it, but just in case, there is the Nerves project: https://nerves-project.org/

As for embedded... I've only dabbled. Yeah you're not going to run Elixir on an Arduino or other very minimal bare metal embedded processor. But the Nerves Project (https://nerves-project.org/) which runs Elixir directly on SBCs is very well regarded. But either way it doesn't matter, since I thought we were talking about web dev, which is where Phoenix and Elixir just make more sense, for me.

For me particularly I like it for things like APIs, Web Platforms (lower resource usage than other languages), and embedded devices via Nerves. However I've also used it on my endpoints to monitor them via Erlang's built in os_mon. Another usage is the distributed nature of erlang can allow you to do things like connect two nodes and run code on a remote node via remote procedure calls. This would allow you to execute something in a nearby geolocated node and reduce latency. Fly.io did a talk on this feature.

Check out nerves, a set of tools and libraries for embedded development with Elixir.

Is this kinda like the Nerves approach but for Golang? (https://github.com/nerves-project/nerves)

Nerves is also popular for embedded.

libcluster is the go-to package for connecting multiple BEAM instances and setting up healing strategies. libcluster provides out-of-the-box strategies and it allows users to define their own strategies by implementing a simple behavior that defines cluster formation and healing according to the supporting service you want to use.

I am using libcluster to connect my nodesI get the following error:

Distributed Elixir can be done with Docker containers too, see https://github.com/bitwalker/libcluster which by default has some Kubernetes support but you can also have third party (or custom) clustering strategies. I've not done this myself but I've seen articles about this a lot during the past years.

Hot code updates for most applications aren't really worth it in my opinion, assuming you do something like blue/green rollover deployments. It's cool that it's possible though. But it requires appup files and afaik Distillery is one of the release tools that has support for it built-in.

On the deployment level, you can use synchronous communication using API-based solutions or asynchronous communication using external solutions (RabbitMQ, Kafka,...) or Erlang/Elixir tools (message passing, pg2, PubSub, Libcluster,...)

Looking throught libcluster code (https://github.com/bitwalker/libcluster/blob/master/lib/strategy/kubernetes_dns.ex#L150) it does seem to require that both nodes share the same basename.
