Amazon Virtual Private Cloud (Amazon VPC) is an AWS service that enables you to launch AWS resources within your own virtual network. Because you can deploy VPCs in separate regions and other VPC components themselves are deployable across different Availability Zones, VPC-hosted environments tend to be highly available and more secure.

In part 1 of this series, we looked at the common components of an Amazon VPC including CIDR blocks, subnets, firewalls, and route tables. We also looked at approaches for how to configure those components securely.
