Am I reading https://instances.vantage.sh/rds/?min_vcpus=4&cost_duration=... wrong. It seams you can get that as a db.t4g.xlarge for ~$188/month.

Still more than 2x the cost, but not nearly $760

$188 without storage and bandwidth.

> for ~$188/month.

Note that this is still the on-demand price.

Although it's still not Apple to Apple, no one (sane) would useRDS 24x7 without RI. That probably brings you down another 50 bucks or so.

The t4g instances are also burstable so running your database with 4 cores under load would either get you throttled or produce more charges.

and the price excludes the 1.5 TB EBS volume

Yeah, tack on another $115 or so for the 1TB of storage. And as a sibling comment mentions, on-demand pricing means it isn't really an apples-to-apples comparison. In almost every case other than a hobby project it feels like the convenience of RDS vastly outweighs the savings of ~$250 you'd get by self-hosting.

A few years ago I managed a 10TB Postgres cluster backing a moderately high traffic site. I no longer even give the briefest of blinks at any of the fully managed database prices that used to make my eyes water.

Because you feel like you got good value for your 10TB DB or because you feel like you got fleeced? Not sure I understand your undertone.

I think the implication is, “I used to manage my own DB instance and I’m now willing to pay anything even vaguely reasonable to not have to do that again.”

Correct!
