Charge for download Get-S3PreSignedURL inside AWS network?

Question

I want to have RDS SQL Server SQL Agent job import data from a S3 Get-S3PreSignedURL source using a Powershell script job step.

Since this is inside the AWS framework (The RDS server is AWS and the S3 link is AWS and both are my account) do I get charged for the transfer of the data from the S3 to my RDS SQL Server instance?

Answer

Hi,
there is no change for transferring the data between S3 to the VPC where the RDS is running as long they are in the same region (https://aws.amazon.com/s3/pricing).

However, if your RDS instance is running on a private subnet you might need to setup a NAT gateway (or 2 for high availability ) to reach Internet and the S3 bucket. In this case you will pay for the NAT gateway.

To avoid that cost you could use a VPC Gateway endpoint https://docs.aws.amazon.com/vpc/latest/privatelink/gateway-endpoints.html that will allow you to reach the S3 bucket directly from the internal AWS network and without the need of paying a NAT gateway.
