> At a payments company, 500 payments per second is considered high throughput and 1000 payments per second is a huge amount of volume.
I realise I live in a strange world when my first thought reading this is "Worldwide? That’s low. Fits in the basic one region, one account concurrent AWS Lambda quota. No need to even ask support for the 10k."
I mean, if you think about it, you can't pay a lot per second, most of people don't have money to throw around that much... How many times do you buy things during a day? Once? twice? Maybe thrice? 6 million payment uniformly in an hour is 1666 transactions per second, overall this tracks.
