If I want to move 400 TB per month out of Amazon, why can't I just proxy it thru 100 Lightsail instances?
Isn't that much cheaper than paying directly per byte? For that much saving it's probably worth figuring out how to do this. It can't be hard.
Isn't it "free" to move data internally to a lightsail instance, as long as both are in the same DC?
There are some answers in the lightsail faq[1]:
1. You're limited to 20 instances per account. They'll increase that number on a case-by-case basis, but probably not if you're planning on proxying all your traffic through those instances.
2. If you delete an instance and create a new one, they share the same data transfer allowance.
3. All data transfer (both egress and ingress) applies to the data transfer allowance.
It may still be worth doing the proxy setup, but Amazon seems to have pretty clearly set up limits to make it less desirable.
