Data transferred “in” to and “out” from public or Elastic IPv4 address is charged at $0.01/GB in each direction.

So, depend on traffic flow.

Hi, Yes, you will incur costs as per https://aws.amazon.com/ec2/pricing/on-demand/#Data_Transfer ``` Data transferred "in" to and "out" from Amazon EC2, Amazon RDS, Amazon Redshift, Amazon DynamoDB Accelerator (DAX), and Amazon ElastiCache instances, Elastic Network Interfaces or VPC Peering connections across Availability Zones in the same AWS Region is charged at $0.01/GB in each direction. IPv4: Data transferred "in" to and "out" from public or Elastic IPv4 address is charged at $0.01/GB in each direction. IPv6: Data transferred "in" to and "out" from an IPv6 address in a different VPC is charged at $0.01/GB in each direction. ``` Note: in you case, both ends will pay the fee in or out for a transfer. Best, Didier

If they were in the same AZ, then it's free. But you mention it is a 3-rd party. So there will be 2 different VPCs. How are you going to make the connection without VPC peering or Transit Gateway even they are in the same AZ?

For the same region but different AZs use cases, CloudFront could be a good option if you have high volumes of data, since there are no data transfer costs between CloudFront and AWS services within the same region. There is also an interesting S3 workaround (if latency is not a concern) where you can sidestep data transfer costs for intra-region, same AZ use cases since most S3 storage classes go by region rather than AZ granularity.

r/AWS_Certified_Experts on Reddit: Inter zone data transfer charges in a region

July 31, 2024 -

When data is transferred between two zones in a region, is it true that you are charged in both the zones (data out in one zone and data in in another zone)? So if 1 GB data is transferred between two zones then you will be charged for 2 GB.

I was checking Azure and GCP documentation and it seems it is not the case with these two providers where you will be charged for data transferred out from the a zone only. Is it something which AWS had for a long time or has it been introduced recently?
