  But there is no paid egress when we are moving data between account within one region, rigth?

    There is. You pay a price for any cross-VPC traffic.

      This isn't true, at least not anymore. You can peer two vpc's and as long as you are transferring within the same (real) AZ, it's free: https://aws.amazon.com/about-aws/whats-new/2021/05/amazon-vpc-announces-pricing-change-for-vpc-peering/ https://aws.amazon.com/about-aws/whats-new/2021/05/amazon-vp... Even peered VPC's only pay "normal" prices: https://aws.amazon.com/ec2/pricing/on-demand/#Data_Transfer 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."
