For example, suppose I have a EC2 server of, say, 4 core 8G memory, then how many people can I support at the same time using this server? I only need voice call and do not need video call, and only need to support at most 4 people in one video chat room.
Actually, I need to support at least 1000 users at the same time. So I wonder maybe I should use a cluster? And how many machines should I buy for that cluster?
Thank you very much for this wonderful library - which is even open source! And thank you for your reply!
