Scaling TURN server

Hi,

I was wondering how to scale the turn server. I can create a turn server by installing
coturn on a seperate server and configuring it in prosody by enabling turncredentials module and configuring turncredentials_host , turncredentials_secret and turncredentials

This works. However TURN can use a lot of bandwidth. Can I just add more turn servers when needed? Is this question maybe better suited to be asked at coturn end, or can jitsi be configured to dynamically add and remove coturn servers like we can jvb.

Or is my thinking completely wrong
