A peering connection enables you to route traffic via private IP addresses between two
peered VPCs
VPC endpoints enable private connectivity to services hosted in AWS, from within your VPC
without using an Internet Gateway, VPN, Network Address Translation (NAT) devices, or
firewall proxies
A VPG is the Amazon side of a VPN connection
Network Address Translation (NAT) is used to translate IP addresses when routing between
subnets that do not have a fully routable address space
