Doubt about billing and transfers between regions of a Public AMI with public Snapshot

Question

Let's suppose this scenario.
- AWS **"User A"** has created a public AMI based on a public Snapshot created also by "User A" at eu-west-1.
- AWS **"User B"** with a different account than "User A" copies this public AMI+Snapshot (because it is public) to a region at ap-northeast-1 in its own account.

After the process, "User A" still have its own AMI in region eu-west-1 and "User B" has its own copy of the "User A" AMI in ap-northeast-1 in its own account.

The doubt is, who pays the transfer of the copy?
- "User A", the originator of the AMI?
- "User B", the one who copies the AMI to its own account and region?

I hope I've explained my doubt correctly.

Best Regards,
Carlos

Answer

Hi

I understand that you would like to understand the pricing on AMI and Transfer costs. You will only need to pay the Snapshot costs,

Who will pay transfer costs ?

* I don't think there is pricing for the AMI transfer 
* AMI are having the Snapshots [Who ever is having the snapshot so they have to pay for snapshot]

When you Copy AMI from "USER A" to different account for the "USER B", It will ask you to create snapshots in the destination. So **Pay only for snapshot**, Do not have to pay for the transfer or AMI, Because AMI's are Free
