Not saying it’s a bad deal. RDS is a great service. I’m saying that suddenly doubling the cost of a service is not a good look unless the value delivered is also doubled. As a customer, in what situation would you find this acceptable?
That's not how markets and pricing work. Prices can go up for any number of reasons, demand is high, demand is too low, past pricing was too aggressive. Amazon has historically been operated with very low profits, maybe Bezos wants to change that?
I'm not sure why you feel offended or deserve a certain price point. Go with some other cloud provider, and if it's too much work, well then there you have it: Amazon has just justified their RDS pricing.
Oh, and thanks for the middle school economics lesson.
