Frequently asked questions
Is inbound data free?
Data transfer into AWS from the internet is free. You pay for data leaving AWS and for some internal movements.
How much is free each month?
The first 100 GB of internet egress a month, aggregated across services and regions, is free. After that, tiers start at $0.09 per GB and fall with volume.
Why is cross-AZ traffic charged?
Traffic between availability zones in a region costs $0.01 per GB each way, so $0.02 per GB moved. Chatty services spread across zones can add up quickly.
How do I cut NAT gateway costs?
A NAT gateway charges hourly and $0.045 per GB processed. S3 and DynamoDB gateway endpoints are free and keep that traffic off the NAT.
