And the first mechanism we're going to use is the original way, years ago, that was the only way for connecting networks. And that's by using public IPs, public subnets, and then just using internet gateways and public DNS to connect all the resources together. This is a perfectly plausible implementation pattern, but it's not necessarily the most secure. Next, we could use a NAC gateway for outbound on one side, and use all public resources on the other, but this is only going to allow one way traffic. We could implement VPC peering, and this allows us to use private IPs between both of the networks regardless of the subnet types. Next we have the Transit gateway. This is similar to VPC peering in that it's only going to support private networking. It is also going to be limited to one subnet per availability zone. Our next option is a custom solution using an EC2 based VPN in our first VPC, and…
