> my usage was 99.2% identical What does that mean? If you're talking about S3, things like PUTs are way more expensive than GETs for example (by two magnitudes). So your usage can be "nearly identical", you can still spend money on precious GETs. Example: Last month I spent around 300 EUR on food. The month before, I spent 150 EUR, yet my food was "97% identical", the 3% being those two times I ordered 75 EUR of sushi takeout. PS: A lot of people get frustrated/confused by AWS pricing and, fair enough, but for a lot of businesses it's often a feature that they allow developers to architect their applications with costs in mind. It's a knife that cuts three different ways.

Yeah, I know how that works. And no, none of that. In my case it was renting a GPU for training a model. No put traffic involved in either of the cases, the data was in a s3 prior to that. It was simply tweaking hyperparameters in the code, nothing more. On both occasions it took the exact same time, exact same to train, exact same resources. There were apparently no changes to the pricing but still. I'm referring to aws's quantum bills as a whole. Never had such issues with gcp... Yet...

  Does cost explorer show no difference in your top costs?

  If you're willing to share the reports you wrote up, I'd be curious to take a look at them.

  Cost explorer should show exactly what was going on.

  In that case, that sounds like Amazon is charging you differently based on how other people are using their resources. In the times of surge pricing, I wouldn't be surprised if they are doing that to make it so they make the same amount of profit, regardless of how much you are directly using, but depending on whether they are getting enough money from all tenants of a particular shared host. So if other people are paying less, they jack up your pricing to equalize things out so at the end of the day, their systems are still hitting their profit target.
