WTF? 80 times the capacity of their entire AWS infrastructure?? That seems insane.

No, the exact quote was:

> Amazon used about 80X the capacity of their entire AWS public cloud

which is probably closer to "the capacity that is available via AWS is a tiny, tiny fraction of their overall computing power.. therefore adding it back in when things are falling over doesn't actually solve any problems."

I don't understand the difference between the wording in your post and the post you're replying to.

I did’t understand either. I suspect it’s the semantic difference between ‘public cloud’ and ‘infrastructure’. I don’t know what that difference is really.

I think they are using the term 'capacity' to mean 'spare capacity'. I.e. that Amazon's entire compute usage is 80x the spare capacity, so scaling even a small amount would consume any spare capacity in AWS. Still, it seems hard to believe.

I interpreted it to mean:

1. he misspoke and meant "80%" of the AWS capacity, which I agree seems implausible. 2. Amazon does not run on AWS because Amazon is 80x more than all of AWS infrastructure. This also seems implausible because of Netflix. In fact, there's an article out there that said AWS exceeded Amazon's capacity within 1 quarter!

I still don't understand what that has to do with autoscaling exactly
