In addition to using the internet to gain access to your VPC via an IGW, you can also connect to it via a VPN connection from your own data center. This enables you to create a link between your own on-premises network and your VPC without using the public internet.
To do this, a "customer gateway" is configured at your own data center, which can either be a physical or software appliance. The other end of this customer gateway then connects a virtual private gateway, which is configured within your VPC in AWS. The VPN connection is then established between these two gateways.

It's very easy to use the wizard to create your VPC as all of these components that we just discussed will be...
