The tech here is from Jelastic.
@girish I have set JitsiMeet up to scale both vertically and horizontally; the search starts from tomorrow to find enough users to load it and actually make it scale!!! But I know people who have started with a similar small instance of Jisti and scaled it vertically - on demand - to 40+ users with great success. No need to start with a 4CPU/32GB RAM VPS to achieve this.
And here is another business using the same underlying Jelastic tech to offer Jitsi and BigBlueButton meetings - of varying sizes - by the hour! It follows logically!
There is a large overlap between the important Cloudron apps and their "easy-to-install, autoscaling" apps: Nextcloud, Gitlab, Mattermost, Jitsi, BigBlueButton, Redmine, WP, Ghost, etc
From these two screenshots, its clear they clearly scale WP very well:
