Aurora Postgres is an interesting product where AWS made significant changes to Postgres storage architecture, however it has a fairly high fixed cost. It seems in many cases RDS Postgres is cheaper and even when using Aurora, using fixed-size instance classes instead of "serverless" autoscaling classes (with ACUs) is a lot cheaper. Fixed Aurora on-demand instances are roughly 17% the cost of ACUs. Fixed instances are usually >= 30% cheaper on top of that if you reserve. Aurora heavily favors performance and availability over cost.

AWS has a decent implementation transactional distributed block storage that they leverage for a few technically decent offerings. Aurora being one of them.

I used to work for a business that was predominantly used by women. Like clock work, at 3pm PS most weekdays there was a spike in traffic as our customers became active on our system. I would love to see the real numbers behind the costs. Is time of day dependency the real price driver here? Are some customers getting more value than others out of this system?

Is 3PM PST when most women sync their in-built RTC?

    3PM is around when school ends for most k-12 schools; if its something someone might check quickly in a free moment at/after work and/or in the car waiting to pickup kids, I can see a big spike from teachers (disproportionately women) and primary child-raisers (disproportionately women) around 3pm.

    To answer, daily peak, 3pm PT to about 11pm PT... That starts 6pm ET, so post work and kids, it's "free time". By 6pm PT(9pm ET) we would be hitting a peak, for the next hour or two and then winding down till 11. It's the prime time for "adult working women" as a demographic.

      Ah I see. So it's just generally the "adult working parent" prime time, but you had a focus on women because they were the service's target demographic.
