A question on hosting a Matrix server on a cheap VPS (discuss.tchncs.de)

Hiya.

Because a certain country I'm a citizen of likes messing with international traffic, I've been increasingly aware of the fact web services can break here overnight. One of the things I've still yet to move somewhere more local (or at least have a reasonable backup plan) is messaging.

Matrix seems to be a decent enough replacement for Discord and Telegram in case things go south, but I'm a total brokie. What would be the be the least resource intensive server to put on a VPS in case I'll need to do it, and would I lose out much in features (say, multiuser voice chats) if I were to use that least resource intensive server?

Cheers.

Mine's running on a VM with 2c/4t 2GB of RAM it shares with my Lemmy instance and it's been working fine. I'm running Synapse, there's more lightweight alternatives as well.

The Matrix servers don't do all that much, it's pretty much just plumbing data streams and storing data. You need enough disk to store all the messages and reactions and enough bandwidth to sync the rooms, and that's about it. Most of the encryption is client-side for proper E2EE, so it just moves data around.
