Scaling OM to 150 concurrent users single room
We are on unbuntu AWS. What would be hardware requirements(approximate) to
support OM to 150 students. We can assume may be 2 instructor webcams and
screenshare or whiteboard. Is there a hardware/performance recommendation
information somewhere online? I did try to find on OM website , found a
multi cast setup but nothing about actual recommendations or suggestions
for hardware as per some load.
Is it possible to support 500 concurrent users? What would be tentative set
up for that scenario? Lets assume that there will be only 1 active room for
now.

What would be the best description for these files. If I was
to explain them in a technical manual what would I say ?
TOmGateway.php - = ?
|_ TOmRestService.php - = ?
|_ TOmRoomManager.php - =?
Thanks,

According to KMS report (please see the link from my previous answer)
KMS should be able to server 50+ users (BUT they uses The test machine was
an 8-core, 16GB RAM instance on AWS. and the CPU was almost fully utilized)
So you might consider to have KMS on separate instance with common network
FS (if you need recordings)

Maxim,
if you have to take educated "guess" for M1 on single OM instance with dual
core 16GB server, just 1 webcam, whiteboard share and student watching and
listening lecture, how many students would you say might work on an
average?
Or are there any community members who have scaled OM to 50+ students,
please share your experiences.

4.0.9 has "theoretical" possibility to work on 150 users
I'm unsure about real numbers due to
1) previously Flash crashed earlier than the limit was reached
2) right now we do not environment to test
Here are the numbers about Kurento and 5.0:
https://www.kurento.org/blog/kurento-media-server-690-libnicer-and-performant
From what I read it should be possible to create Kurento cluster to scale
But I never done that yet :(((

Latest 5.0 M1. We are just getting started so if it's better we will use
previous version. I believe webrtc will be easier on server load.
How does one provision hardware for something like this? Trial and error?
