I am currently investigating into writing a real time chat application in Elixir/Phoenix. I have a few queries before I jump into choosing a particular technology. Please see and answer my below queries -
Is WebSocket the standard for writing real time chat applications or can I use gRPC or is there any better transport mechanism?
How does Elixir/Phoenix Channel compares to other technologies or services like
- Action Cable
If I decide to go with Elixir/Phoenix Channel, how can I run multiple instances of chat application on Kubernetes pods? Can someone points me to any document/article on this deployment part?
Is there any hidden problem using WebSocket with multiple instances of chat applications that I should know about - like security/stability/scalability/performance?
Awaiting some response.
