ok I've heard this before, but I've never had a problem with it. walk me through it.

I get the expense if you're running a lot of egress (e.g. to replicate cross region), but given a single AZ setup, how does a NAT run up massive charges?

traffic coming from an LB doesn't count as NAT traffic does it? your instances have to initiate everything running through the NAT, yeah?
