This is a typical VPC architecture where you could create and run an application. Throughout this book, you will add more features to this VPC, including creating servers and simple code to run a small application.

You have two options to create these VPCs, depending on personal preference. You can use the AWS Management Console, or you can use the AWS Command Line Interface (AWS CLI).

The first step is to create a VPC. Rather than using the default VPC, creating one manually will help you to turn the theory you have learned in this chapter into real-world knowledge:
