How expensive is the AWS RDS transfer cost?
I have a social networking site hosted on AWS. Am I going to charge at all for RDS transfer fees (since RDS will connect to EC2 through AWS)? Does this mean that I need to pay the EC2 transfer fee? How expensive can database bandwidth be compared to image bandwidth?
Really appreciate any input.
Thank.

There are also data transfer charges from RDS to ec2 instance, but this depends on your installation. According to AWS docs
- Data transferred between Amazon RDS and Amazon EC2 instances in the same AZ is evaluated as follows
- Using a private IP address is free of charge.
- Public or Elastic IP usage is $ 0.01 per GB
- Data transferred between AZs to replicate Multi-AZ deployments is free.
- Out-of-VPC Amazon RDS DB Instances: There is no data transfer charge for traffic to or from the Amazon RDS DBA instance for data transferred between an Amazon EC2 instance and an Amazon RDS DB instance in different AZs in the same region. You only pay for data transfers on or off your Amazon EC2 instance, and standard Amazon EC2 Regional Data Transfer rates ($ 0.01 GB I / O) apply.
- Amazon RDS DB Instances Within VPC: For data transferred between an Amazon EC2 instance and an Amazon RDS DBA instance in different AZs in the same Region, Amazon EC2 Regional Data Transfer charges apply on both sides of the transfer.
You can check what setting you have and for a complete list of prices refer to https://aws.amazon.com/rds/pricing/ .
