I come from a background in IoT and backend work.
Mostly, I got around doing NodeJS, C++ and Python wherever possible.
I just got my hands on learning Elixir + Phoenix ! (yay)
I did a basic project with a small crud that updates some liveviews.
Basically, I used to deploy an MQTT broker, EMQX to pass messages around my backend services. What was cool with EMQX was the fact you could set up «broker forwarding».
Meaning, if you had many distributed brokers, if a client posts a message on TOPIC A on broker 1, other subscribers of TOPIC A on broker 2 would also receive the message.
My question is: if I had to deploy many instances of my app on 2 computers,
would there be any way to replicate the EMQX forwarding behaviour?
If so what are the specific terms I should look and google for ?
