@igeljaeger you will certainly need a bigger drive for uploads since pleroma can't into compression, but for the database 30GB should be fine if you don't forget to prune and vacuum full (can be done online with pg_squeeze or pg_repack) it regularly. for everything else, can't tell since I never had that much users, 1 core and 2 gigs certainly isn't enough though. I would use a host that has flexible storage and just scale up storage/hardware if it turns out not to be enough.
