How to Efficiently Handle Concurrency in Erlang for Scalable Real-Time Applications

Hi, I’m currently developing a real-time chat application using Erlang and aiming to implement a robust concurrency model. While I’m familiar with the basics of spawning processes and message passing, I’m seeking guidance on best practices for managing many concurrent user sessions efficiently. Specifically, how can I structure my application to ensure scalability and fault tolerance as the number of users grows? Are there design patterns or architectural considerations in Erlang that I should be aware of in order to handle this effectively? To assist in this endeavour, here are some resources I’ve found:
