> RDS is a particular racket that will cost you hundreds of dollars for a rock bottom tier. Again, Digital Ocean is below $20 per month that will serve many a small business. And yet, AWS is the default goto at this point because the lockin is real.

This is a little disingenuous though. Yeah you can run a database server on DO cheaper than using RDS, but you’ll have to roll all that stuff that RDS does yourself: automatic backups/restores, tuning, monitoring, failover, etc. etc. I’m confident that the engineers who’ve set up those RDS servers and the associated plumbing/automation have done a far better job of all that stuff than I ever could unless I spent a lot of time and effort on it. That’s worth a premium.
