What would be potential problems with building "private" Ethereum network on AWS?

by Nicholas   Last Updated January 20, 2018 20:28 PM

Suppose I have two EC2 instances on AWS that are running geth nodes. They have the same genesis block and are in synchronization because peering is setup with open port 30303 (by default is for peering among nodes).

What would be potential issues with this setup? Wouldn't others be able to access from outside the network by hitting the open ports?

Also any issues with scaling?
