In the previous section, we learned about private, public, and Elastic IP addresses, and how they are assigned to the ENIs attached to an instance. Following are a few components that are important in the Amazon VPC:
In this section, we're going to discuss subnets and route tables, and how a route in the route table can make a subnet public or private. Then, we'll talk about NAT instances and NAT gateways, to give instances and private subnets access to the internet.
