300 participants in one conference

Hi community,
If I install the jitsi on vm(8 GB / 4 CPUs,1Gbps),and I want to create a conference for 300 participants with video,How many jvb/jicofo/prosody servers do I need?
Please give me some suggestions, thanks

In addition to the main node (containing Jicofo, Prosody and Nginx), you’d want to have 2 properly loadbalanced JVBs, just to be safe.

Thank you for your answer!
