BigBlueButton feedback :
A French university with OpenStack virtualized servers. The servers are a fronted “Scalelite” with 8 VCPUs and 8 GB. A “greenlight” frontend with 8 VCPUs and 8 GB of RAM (not open to users). 10 BigBlueButton “backend” with 12 VCPU and 8 GB of RA.. A shared NFS volume for the publication of recordings 200 GB. For storage, it is a NETAPP bay with mechanical disks with some SSD. There are two remote databases on shared servers for grennlight and Scalelite. ( DBMS postgresql 11 standalone shared with other applications).
This infrastructure makes it possible to have 2,000 users simultaneously (200 per server). On the other hand it is possible to quickly deploy new backends to increase the load.
To reduce the load they opted for the following setting:-ebcamsOnlyForModerator:”true” – muteOnStart’true”- allowModsToUnmuteUsers”true”.
