Which statement about AWS data transfer pricing is generally correct?
A question about choosing the correct statement on AWS data transfer pricing.
Inbound transfer from the internet is charged at the same rate as outbound transfer.
For AWS data transfer, inbound transfer from the internet is generally free.
Charges center on outbound transfer to the internet, so the statement that inbound is charged at the same rate as outbound is wrong and incorrect.
Within the same Region, traffic that crosses AZs is also free.
Even within the same Region, data transfer that crosses Availability Zones is generally charged.
It is NOT the case that everything within a Region is free, so this statement is incorrect. When estimating costs for a multi-AZ architecture, also account for inter-AZ transfer.
Outbound transfer to the internet is generally charged, while inbound transfer is often free.
Correct. In general, data transfer out from AWS to the internet (outbound transfer) is charged, and transfer in from the internet (inbound transfer) is often free. When estimating costs, pay attention to the amount of outbound data transfer.
Transfer between Regions is free because it stays within the AWS network.
Inter-Region data transfer travels over the AWS backbone, but inter-Region (cross-Region) transfer is charged.
Staying within the AWS network does NOT mean free, so this statement is incorrect. For things like cross-Region replication, plan for transfer costs.
Data transfer pricing: outbound (out) is charged / inbound (in) is often free / inter-AZ and inter-Region transfer is also chargeable. When estimating costs, watch the amount of outbound transfer and traffic that crosses AZs and Regions.
