Options for connecting two Elixir apps?
Hi all,
I’m playing with designing a multi-tenant SaaS pet project using the Control Plane / Application Plane model. There will probably be two main web apps (control and application planes) in Elixir/Phoenix. The control plane will run on a single node (private network, not accessible from the internet, separate DB), while the application plane will be multi-node (accessible from the internet, separate DB).
The question I have is how to enable communication between these two planes/apps. Most examples I’ve found focus on microservice architectures based on HTTP APIs. Others suggest message queues or event buses. Given the strengths of BEAM, I’m wondering:
What are the options BEAM-native or preferred mechanisms for loosely coupled communication between two Elixir applications?
Looking forward to insights from anyone who has tackled something similar!

If they’re not clustered, you’re outside of the BEAM native umbrella aren’t you? Then you can choose between HTTP, Websockets, grpc, etc.
I’ve used Phoenix channels to do multiple client to server connection using Slipstream. I wanted to know when they’re connected and channels provided the tools for that.
