Compare Amazon's (at least network) pricing to Google Cloud or Azure and its roughly competitive.
The scale of the networks these companies are building is unlike any of the novice-level stuff companies like Hetzner deploy. As one example, in one region AWS has deployed 5 Pbps of inter-AZ fiber. They build all of their own SDN switches/routers, all the way down to the chips now, for maximum performance and configuration with the AWS API. And don't forget, they maintain a GLOBAL private network; companies like Hetzner or DigitalOcean just peer to the internet to connect their "regions".
I'll keep saying this on HN until people start listening: If you buy AWS then complain about price, you might as well go buy a Porsche then complain about the price as well. They're the best. Being the best is expensive.
