Is there any way to providing video conference supporting large number of participants in conference (around 2000). The conference will be held in future and I should guaranty the performance. What is System Requirements for server. Does anybody test "Lync Server 2013", "apache-openmeeting" or "BigBlueButton"?
I've messed with BBB, though no where close to those numbers. As the presenter, you can prohibit participants from sharing their video or audio, making it a one way presentation.
I have a gut feeling though, that the server requirements would be significant for that many participants. We ran it on an old HP G3 and it worked , but slow for a dozen participants.
From their FAQ:
Personally, I'd probably looking into a SaaS solution like Webex, GoToMeeting, or the like. There are probably at least a half dozen solid options. Without having done it before, I'd hate to have sole responsibility for a conference that big.
