In order to work with the ELB example, this SG would need to open port 80 (actually the specified ELB port) to the world as well. Obviously, that's probably not the practice you'd really use, but that's the only simple way to do it. 

I'm inclined to omit the security group, as it is AWS specific, but if it is included it should at least work with the rest of the example.
