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.

It seems like he's having a database for each app.

		Could be, but this doesn't change my statement: if it's acceptable from the business standpoint there is nothing wrong with this setup.

> 30 db instances

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

		Ah yes that's probably true, but still having 30 apps in a single db instance doesn't seem better...
