I run my own instance, the benefit is privacy and reliability. Everything is controlled on your own server. You also aren’t reliant on someone else running an instance that could go down at any time, either permanently or an outage. Been a problem with Lemmy.ml recently.
How is your RAM/storage usage? I'm interested in setting up my own instance (no communities, just a username that will always be here) but don't want to upgrade my VPS again. I already had to do that spinning up a Mastodon server.
I was asking myself a question, if you comment like you did here
Is it saved in the server on which the original post is, or is it saved on your server?
Kind of both. His server has a mirror of the community. When he comments it gets saved on his server and the his server communicates with the original server. In turn the original server also communicates his comment with other federated servers.
If data is migrated from server to server, as the community grows in size, the data to be maintained on each server also grows in size? Also i've seen some servers allow the creation of new users/communities, but some don't... whats the point of that if the data is just replicated anyway?
