For one of the application, we are planning to go for multi-region, I want to have two EC2 Linux instances in different regions and have a load balancer. Both are primary servers and I want to set up synchronization between these two instances so that if load balancer sends a request to any of these servers to update\delete\add a file, the other server would also be updated.
I was looking at EFS which only spans multi-availability zone. Does Amazon offer anything to provide synchronization between two primary Ec2 instances? If not, Is there any other way I can set up synchronization between these two primary servers.
