Sorry, I could only post in Off-Topic...
I was curious how Cloudron handles scaling. I was considering using Cloudron for about 50,000-100,000 users, maximum of 2,000-5,000 online at a time. 300 instances of a wiki, 300 forums, (300?) synapse servers, and 300 SOGo, Radicale, Easy!Appointments, or some other calendaring software, and one primary (large instance for everyone) Element Client, forum, wiki, and calendaring. This is for federating 300 organizations.
How well could Cloudron actually handle all of that? What approach would be optimal? Could Cloudron use managed databases for instance to scale better? What sort of VPS size would I likely need at that point?
