A few years ago I built something similar to this, in that it used the JSON API definitions to automatically scrape the entire AWS API surface area. But I was doing it every 5 minutes and storing the result in postgres instead of it being o

In the benchmark it says they are using an m5.8xlarge, which don't have locally attached SSDs. So presumably this is against gp3 or io2 volume. In which case I am surprised that wasn't the bottle neck of the test. Do none of these

They replicate the data by some amount within an availability zone using some form of forward error correction. They look at their machine/hard drive irrecoverable failure rates within that facility and get 99.99% durability. Then they

Yep, usually gets picked up when a company ends up getting SOX compliance before going public. While OFAC sanctions are not strictly speaking part of SOX, every audit I've seen ends up putting them in place anyway.
