Noob question: How much RAM does my VPS need if... (sopuli.xyz)

I plan to have the following services running concurrently on it:

A VPN (OpenVPN or Wireguard)
A very lightweight personal website
A Nextcloud instance (25GB storage max)
A Vaultwarden instance
An Invidious instance
A Matrix server
A Lemmy instance

I'm unsure if these would be private or public instances. But I'd be curious to hear any thoughts on how much more space I'd need for public instances too, if you'd have a sense of that.

I currently have a VPS with 2GB RAM + 50GB storage. Would that be enough? Thanks in advance!

2gb will be probably insufficient, mainly because of Matrix Synapse. If you avoid joining any large communities it might work, but if you are not doing that you might as well use a XMPP server which is better anyways.

A small Lemmy instance will take around 500-1000mb RAM so that will likely work but use a significant portion of your RAM.

Thanks for the info. I wasn't really able to find a clear answer elsewhere.

This is my droplet with 1GB of RAM only running lemmy:

free -m
               total        used        free      shared  buff/cache   available
Mem:             964         386          68         141         509         219
Swap:           2047         310        1737

So expect at least 1GB for lemmy with postgres included when you include spikes etc.
