Is CDN needed for Antmedia? How to scale for conference type server?

[ruell magpayo]

Our requirement is bidrectional stream, like a conference.
there is a maximum of 10 people in a room BUT the server should be hosting multiple rooms.

by the nature of CDN servers, it can only process HLS or RTMP and there are documentation/tutorials in Antmedia that do so, 

but my question here are,

1. if using webrtc, is CDN needed?

2. If no, then how do we scale the streaming? Should it be just Antmedia Server deployed in multiple location and they route/relay with each other? 
3. Does using CDN only works for one directional stream (concert or movie watching) and not bidrectional Many to Many conference?

Hi,

1.You can't use CDN with webrtc in the current situation

2. You can use AWS auto-scaling or you can add streams manually to an Ant Media cluster, see detailed information in; https://github.com/ant-media/Ant-Media-Server/wiki/Clustering-&-Scaling , https://antmedia.io/ant-media-server-cluster/

3. CDNs are not designed for streaming purposes initially, they are distributing http requests and since HLS works with http requests it is a great fit for CDNs base architecture. However, there are some work going on to make CDNs support Ant Media webrtc.
