Server sizing recommendation for 30 simultaneous 1-to-1 BigBlueButton classes

[Latif Ur Rehman]

Hello BigBlueButton community,

I am currently using BigBlueButton for online classes and I would like to get some advice regarding the required server resources.

My current usage pattern:

• Around 30 classes run at the same time

• Approximately 60 users connected simultaneously (2 users per class)

• Classes run Monday to Friday

• Daily usage window is from around 8 PM until 3 PM the next day

• All classes are 1-to-1 sessions

• Around 25 out of 60 users usually enable their webcams

• Chat system is disabled

• Polls are disabled

• Notes sharing is disabled

• Every meeting is recorded

• Whiteboard is used regularly

I would like to know what server configuration would be recommended for this workload.

Specifically:

1. What dedicated server specifications would be enough for this usage?

   • CPU cores

   • RAM

   • Storage type (SSD/NVMe)

   • Network bandwidth

2. If using a KVM-based VPS instead of a dedicated server, what minimum resources would you recommend?

3. Are there any important configuration changes required for better performance with this type of workload?

4. Would a single BigBlueButton server be enough, or should I consider multiple servers/load balancing for this number of users?

Any recommendations from people running similar workloads would be greatly appreciated.

Thank you.
