I think you're absolutely right for iptables, as I didn't changed anything to use the X-Forwarded-For IP, so this part might have been fully useless.
About the EC2, it's because it's managing the SSL for us, and we used to have two servers behind it.
Everything could have been planed way better (cached, written with a fancy language...), we could have had 10 mil requests/µsec... the main idea was just to get tell how we tried to manage the situation, with the website and skill we have.
I also think my testimony is nearer to what most of web dev can be confronted to, in contrary to one Cloudflare/Gihub BS press release written by 10 experts to increase valuation :p
