Server Configuration

Hi,

We have installed jitsi at AWS instance. after creating 3 meetings, we want to use that meeting link at other website (Another Instance of AWS).

What should be the server Configuration of both Instances to manage
3 meetings, 1 will have 200 people, 2nd meeting will have 400 people and 3rd meeting will have 500 people.

Please update server configuration so it should be completely smooth.
