University of Toronto ☛ Realizing the hidden complexity of cloud server networking
That was when I realized how complex all of the infrastructure for this networking has to be behind the scenes. The cloud provider is not merely operating a carrier-grade NAT, which is already non-trivial. They're operating a CGNAT firewall system that can connect a public IP to an IP on a specific internal virtual network, where the IP (and subnet) aren't unique across all of the (internal) networks being NAT'd. I feel that I'm reasonably knowledgeable about networking and I'm not sure how I'd even approach designing a system that did that. It's different in kind from the NAT firewalls I work on, not merely in size (the way plain CGNAT sometimes feels).
