Below you can see how easy it is in AWS to select a VPC and then click a button to “Create internet gateway” in order to grant internet access. If a customer-facing application is moved to the cloud in order to improve performance, a direct internet connection using a gateway can be put in place.

Think about what information you’ll need to find out which EC2 instance hogged a VPN connection or what service drove up costs on your NAT gateways, and so on. You simply can’t configure flow logging on internet gateways, which would seem like an obvious place to do so. AWS does not let you configure flow logging for internet gateways.

Designed before the dawn of the commercial Internet, the Border Gateway Protocol (BGP) is a policy-based routing protocol that has long been an established part of the Internet infrastructure. In other words every IP address that you can get to on the Internet is reachable because someone, somewhere, has advertised a route that covers it.
