He's doing all of that on a single server?!

I'm not against vertical scaling and stuff, but 30 db instances in one server is just crazy.

It's an average of 8GB per database, I guess he serves multiple clients and decided to "segregate" each client on its instance. If it's acceptable for the business it's nothing wrong with his setup.

> 30 db instances

They didn't say that and the article didn't allude to that. 1 instance with 30 databases.
