I will rent a v-server today with those specs: 2 CPU cores, 4GB RAM, 80GB disk space
I think it’s enough to run normal websites and even a game server, but I have no experience with the Fediverse.
Is this enough to run a few fediverse instances, like Lemmy and Mastodon or even others?
How much resources does Lemmy need in particular?
Thank you for your help.
That’s more than enough for when you’re just starting an instance. I’d even knock that down to 1 core 1 GB RAM, which is like $5 a month on a host like Linode or DigitalOcean. The reason Lemmy.ml is experiencing trouble is that it’s one of the largest instances, we didn’t have problems until recently. The great thing about a VPS is that you can upgrade whenever you want, so I’d recommend saving some money by getting the cheapest one until your instance starts getting a lot of users. Every VPS host I know of shows you the resource usage history, so you can monitor it once in a while and upgrade when one of the stats is getting close to 100%.
