Approximately how much bandwith is required per user-hour on a call?

[skohan]

I’m doing an evaluation about whether my company would like to consider hosting Jitsi on our AWS infrastructure for internal use, and the main consideration is cost. Are there numbers available about how many GB of bandwidth are used by Jitsi on average? If I have that I can do a back-of-napkin estimation about whether the cost is feasible for us.

Also, from this source: https://jitsi.org/jitsi-videobridge-performance-evaluation/ it looks like a single VPS or docker container should be able to handle several hundred simultaneous streams comfortably. Is that assumption correct?

Bandwidth cost modeling

Hey, this really depends on a lot of factors. Here is a very rough estimate: 5 x Chrome with simulcast in 720p: in: 5*4=20 Mbit/s out: 5+4*0.2=5.8 Mbit/s (one person on large and 4 thumbnails) approximately 26Mbit/s so for an hour ~12GB * 0.09 = $1 5 x Firefox (no simulcast), this changes only what goes out of the server it will be same as input so 40 Mbit/s, and for an hour ~18GB * 0.09 = $1.6 And these are very rough (if correct) and in best conditions. If you change the UI to Brady bunc…

This had been discussed several time in the comunity

I don’t really understand this math. Shouldn’t each user be 4Mbps up and 5.8 down, not 20 up and 5.8 down?

These calculations are from the servers point of you. As cost you are caclulating for server.

Ok so this 12-18 GB/Hour is a rough estimate for the total transfer cost for a 5 person conversation, is that correct? As in roughly $1-$2 total per hour, not per user per hour
