I have my AWS EC2 setup in different regions, say one in Oregon, and another one in Ireland.
I want to send a UDP message from Oregon to Ireland.
What IP address should I use in this case?
I have both private IP addresses and public IP addresses for Oregon and Ireland.
My system is ubuntu 12.04 64bit.
I know that within EC2 network, we can use private IP address, for example, two instances/servers in Oregon. But how do we deal with two instances in different regions?
Can anyone help?
