I’ve brought up a new KBIN instance, https://feddit.online
It’s administrated from the Greater Boston, Massachusetts area. Everyone is welcome to sign up, so long as they follow the rules
I now, because I must be crazy, have 4 Fediverse servers running.

DB would be a big one, no? Not sure what Kbin is using, but DB costs tend to be meaningful as well, especially since depending on how the app is designed the usage requirements can sort of parity the app hosting requirements itself. Plus storage, but that can be more variable depending on how robust you want it to be. Ie S3 is pretty robust but it’s expensive, etc.
It uses PostgrSQL. I’m paying an extra $2/month to keep the database on an external drive. So far, it’s only using 151 MB of the 20 GB. I don’t think I’ll run out of space for a while. But, this weekend, the larger server I move to will come with an 80 GB drive so I don’t think I really need an external drive. Currently, the DB doesn’t cost anything extra.
But, you reminded me, there is a cost to keeping a database backup. My server is in NYC1. I have an S3 bucket in NYC3 that will be use to hold 5 days of daily database backup, compressed. I pay $5/month for the 250 GB Digital Ocean S3 bucket, I believe.
