Best server for 100 conference and each one with 30 participants
meet.jit.si is using c5.xlarge servers from amazon
1 node for jitsi-meet and additional jvbs (2 or 3) connected as MUC in aws auto scale group
As of bandwidth? Is this old estimate still valid? For 30 participants the required bandwitdh would be around 500Mbit/s?
Yes, those estimates are correct. You have all sending simulcast hd (4-5Mbit) per participant and for server upload you have again one hd per participant and several thumbs. Firefox changes the server upload with a lot if sending hd video.
2room with 30participants in each requires a server with 1000mbit/s bandwidth?
in our country, hosting offers 50mbit/s bandwidth for $1,200/month,
or number of rooms does not affect?
you can check out Bandwidth cost modeling to calculate for whatever environment. best way is to use dynamic server where you can pay as per your use.
