We have a huge data say 1000GB that will need to move from one EC2 instance in us-east-1a to us-east-1b using private IPs.
Problem: We are planning to setup multi az MySQL cluster which will be having 1 master and 5 replicas spread across different AZs. But we are concerned about the data replicated across to maintain the master-slave setup.
We wanted to know what would be the total cost incur during this operation in data transfer amongst different AZs?
Note: We have a NAT gateway to communicate to the internet from the instances which are in private subnet. These instances are in the private subnet.
