Very few of AWS's costs are in the hardware. Nearly all of Hetzner's costs are in the hardware. That's why AWS, and Azure, and GCP are so much more expensive.

Margin is a really weird statistic to calculate in the "cloud". Sure, you could just mortgage the cost of the silicon across N months and say "their margin is huge", but realistically AWS has far more complexity: the costs of the datacenter, the cost of being able to spin up one of these 32 core EPYC servers in any one of six availability zones within a region and get 0 cost terabit-scale networking between them, the cost of each of those availability zones not even being one building but being multiple near-located buildings, the cost of your instance storage not even being physically attached to the same hardware as your VM (can you imagine the complexity of this? that they have dedicated EBS machines and dedicated EC2 machines, and yet EBS still exhibits near-SSD like performance?), the cost of VPC and its tremedous capability to model basically any on-prem private network at "no cost" (but, there's always a cost); that's all what you're paying for when you pay for cores. Its the stuff that everyone uses, but its hard to quantify into just saying "jeeze an EPYC chip should be way cheaper than this"

And, again, if all you want is a 32 core EPYC server in your basement, then buy a 32 core EPYC server and put it in your basement. But, my suspicion is not that a 32 core EPYC server on AWS makes zero margin; its that, if the only service AWS ran was EC2, priced how it is today, they'd be making far less profit than when that calculation includes all of their managed services. EC2 is not the critical component of AWS's revenue model.




Margin calculations include all that. And I suspect most of AWS's marginal cost is _still_ hardware.

The marginal cost of VPC is basically 0. Otherwise they couldn't sell tiny ec2 instances. The only cost differences between t3.micro and their giant ec2 instances are (a) hardware and (b) power.


> The marginal cost of VPC is basically 0. Otherwise they couldn't sell tiny ec2 instances.

That's not strictly true. They could recoup costs on the more expensive EC2 instances.

I have not idea what the actual split is, but the existence of cheap instances doesn't mean much when Amazon has shown itself willing to be a loss-leader.


So what you're saying is kind of the opposite of a marginal cost.

If they are recouping their costs, it's a capital expense, and works differently than a marginal cost. AWS's networking was extremely expensive to _build_ but it's not marginally more expensive to _operate_ for each new customer. Servers are relatively cheap to purchase, but as you add customers the cost increases with them.

If they're selling cheap instances are a marginal loss, that would be very surprising and go against everything I know about the costs of building out datacenters and networks.
