Hi there Maxim, Thanks for getting back to me. I've already sent an email to Sebastian.
The clustering approach "looks" relatively straight forward as per the OM site recommendations (and is something I am going to look at in more detail over the weekend).... but I am REALLY interested in trying to implement the three different types of media streams: listen only, webcams, and screen share over 3 KMS servers, as suggested in BBB (which as you may know uses Kurento / WebRTC). Apologies for bringing up BBB but it appears to be the only alternative that uses similar technologies that has addressed this issue. KMS limitations have been talked about over the last year or so - for example... From what I recall, a standard OM / KMS setup can deal with around 300 media server connections. Therefore a group of 5 people sharing audio and video would in theory use 125 of these connections. (5 audio x 5 video x 5 people) but that will grow exponentially if you have 7 users (sharing audio and video... (7x7x7= 343). You might recall last year that I reported on a physical test on one of the OM servers and I got about 9 users (audio and video) working in the same room before things got a little shaky - but let's be honest - having 9 or 10 users sharing audio and video at the same time can be a little messy given the fact that their video pods might unnecessarily take up a lot of "landscape" on the screen also... but I would feel more relaxed knowing that if I have 7 - 9 students in one room and a teacher teaching 7 - 9 students in another room that the server isn't going to go down... irrespective of how good an AWS instance I set up. Last year, there was a time last year when I had 3 classes running concurrently and unfortunately everything crashed. The one time only. Memory usage spiked... but it all boiled down to KMS, it seems. This led me to start looking into everything in more detail, for obvious reasons. After all the time and effort I've spent in experimenting and giving some casual feedback regarding OM, I think simply moving to a commercially OM hosted environment would defeat the purpose of the learning curve I have been on (apologies Sebastian, I mean no disrespect). Anyway, if there is anyone out there that can give me any pointers on how to spread KMS activity over 3 servers (over a single OM instance), I'd appreciate it, paid or otherwise, let me know. This has been a great experience and I'd like to continue my learning curve on this as much as possible. I think this would open a gateway to a lot more conversation and discussion.... a lot more ideas and a solid way forward with users and for OM. Over the years I've seen users achieve what they need to achieve and then disappear from the User List once they've accomplished (or not). Anyway, I digress. For reference the following links are the main ones I've come across that have sparked this interest: https://docs.bigbluebutton.org/admin/customize.html#run-three-parallel-kurento-media-servers and https://github.com/bigbluebutton/bigbluebutton/blob/master/bigbluebutton-config/bin/apply-lib.sh Any suggestions from anybody would be appreciated. I look forward to ANY suggestions on this matter. Please drop me a line either via the forum or directly. All the best. Denis.
