Ec2 classic was dirt simple. You basically were on a big public lan it felt like. If I remember right there were some issues with folks running scans / abuse originating inside AWS that felt like got a touch slow of a response - then at some point it all cleared up? I remember hardening internal systems as if the they were public which was a good practice even as vpc arrived. They might have gotten a default public ip as well?
I used google app engine which was orphaned (at least version I tried) so that was a clear contrast w AWS.
