Networking with the Virtual Private Cloud

In AWS, the core networking component is the Virtual Private Cloud (VPC). It serves as a private, layer 2 isolated networking layer that allows us to build applications in the cloud. VPCs can be connected to each other, on-premise locations, and AWS services, and give us a lot of flexibility when it comes to choosing built-in and custom security solutions.

This chapter will walk you through all you need to know about VPCs. First, you'll install and configure a basic VPC. Then, you'll learn about its networking components and even set some of them up. Finally, you'll engage with some best practices to ensure that you not only know everything about VPCs, but also learn how to use them in the best possible manner.

The following topics will be covered in this chapter:

• Introduction to the VPC
• Working with VPCs
• VPC networking components
• Best practices
