Recommended hardware requirements for running BBB server

[Arif Zaman]

I will have to run a BBB server with 50 users supports, and each will
share their webcams. Can anyone please share your thought with
recommended hardware details for running BBB server on Ubuntu Server
10.10?

Thanks,
ARIF

Any basic box that meets the faqs above will work... Or you can use
a c1.medium EC2 Instance with 5 compute units.

The real issue is Network bandwidth... make sure you have adequate up/
down speed.. This wont run on a residential cable/DSL connection
that is upload limited.

if you don't have a good network

Thanks for your response!

I already read out the FAQ sections. But at this point, I want to
know, from a person who have this sort of deployment experience, about
the recommended hardware specifications for running BBB server with 50
users supports by considering audio/video processing as well.

Airf,

For the upcoming BigBlueButton 0.8, we recently did a stress test of
the improved audio code on a Xenon 3450 quad core running
2.66 Ghz with 4G of memory using an internal build of 0.8. We were
able to support 60 simultaneous users with many sharing their webcam.
For test results, see

http://groups.google.com/group/bigbluebutton-dev/browse_thread/thread/3c7ce9815a9800c3

To understand what we meant by 'improved audio', see

http://groups.google.com/group/bigbluebutton-dev/browse_thread/thread/a36d61df9b9fc45b#


In the upcoming BigBlueButton 0.8, the default transcoding using speex
will move the bottleneck for BigBlueButton to the CPU as the number of
users increase. Our current version (0.71a) of BigBlueButton uses a
different method for transcoding the audio, see

http://code.google.com/p/bigbluebutton/wiki/FAQ#Why_is_there_a_delay_in_the_audio_when_I_use_VoIP?


Also, check out this post from a user running a 0.71a server

For 0.8, we'll let administrators switch between nellymoser and speex
codec for transcoding audio on the BigBlueButton server.

Finally, there is no hard and fast formula for provisioning a
BigBlueButton server -- it really depends on your use case scenario
and whether you have lots of voice (CPU intensive) and lots of video
and desktop sharing (bandwidth intensive). Bottom line: Use a
dedicated server with a fast quad core CPU and lots of memory.

We recommend you run BigBlueButton on Ubuntu 10.04 32-bit or 64-bit
(not Ubuntu 10.10).

Regards,... Fred

Google results in tons of thoughts on this.
http://red5.electroteque.org/dev/doc/html/SystemRequirementsForRed5.html

And of course, it's pretty simple to upgrade the hardware as you go.
So far, in playing with this as an end user, in terms of this question, looks like an easy upgrade path.

Thanks for all your reference. It will really help me for provisioning
a BBB server.

I have another question...............is there any limitation of users
in the conference. Means how many maximum people can come into the
conference at a time???

[Arif Zaman]

Gaurav,

There is no built-in limit on the number of simultaneously active
webcams.

...ARIF

I've helped set up a BBB conference that had over 150 simultaneous
connections, though none of them were webcams (just a shared
PowerPoint presentation with audio from the presenter, questions
submitted by chat). Only real issue that came up was a significant
timelag advancing through PPT slides.
