alt Hacker NewsThat Amazon story is a misnomer. They just saw an opportunity with the tech and hardware they had to make a new offering for customers. It's not like they could just offer their spare capacity, then eg at peak US time snatch it back for the retail site
For many years, I watched my apps performance on AWS suffer in December around all the holiday sales. They might not snatch it back but they probably saturated it during high demand periods.
