Jitsi Self hosted Server

Hi Jitsi Team,
When we self host Jitsi meet app in any of the servers(example: AWS or DigitalOcean) then all the data traffic like public messages, private message, video streaming, etc., are managed only by the server to which I have deployed? Since Jitsi-meet uses few other libraries for its functioning, I am bit confused, Is there any possibility that it communicates to Jitsi owned servers or it is complete isolated to only my own server.
