That's what's so beautiful to me... someone had this crazy idea to sell spare cycles, and now it's the backbone of not only the company, but an entire market segment.

Don't know who really thought of it, or designed it well enough to make it work, but hope all those folks were well, well rewarded.

I've heard this too, but I don't think it can possibly be true. That would mean that, at the start, any service or VM etc. you started on AWS would only work during non-peak Amazon hours. So your website or app would be down if the traffic to Amazon's website ramped up. I can't imagine many companies going for that offering. If that was the product that AWS originally offered I can't imagine it would have been successful.

While that's true, at the time I read this "peak Amazon hours" were a few hours on cyber Monday. In fact, that's probably still true.

I imagine peak involves scaling up the total number of instances, and the house of cards falls down without you growth.

Disclaimer: I work in non-aws amazon, and my imagination is my own.

Except there has been a wall between AWS and Amazon Retail since inception. Only much later did Retail start using AWS. They were buying massive amounts of servers specifically and only for AWS for many years. I would agree that it increased economies of scale for the servers purchased by Retail in addition.

I could be wrong, but I was fairly sure I got the order of development correct. But I'm basing it on memories of the original news reports from back in the day, so I could have misremembered.

>Amazon didn't invent AWS because they were more forward looking.

>Amazon invented AWS because they had idle computers most of the time to handle peak load, and they thought it would be a good way to monetize them.

That is forward looking.
