In the same way as we create dedicated and private networks within an organization, where computers in a network share network devices such as routers, switches, and so on, we can create a VPC when we create a new account in AWS. A VPC makes it possible to shape similar network infrastructure as we can shape it in our own data center. The difference is, it is a virtual environment within a public cloud wherein the virtual network is logically isolated from other similar networks within the public cloud.
This chapter covers the following VPC components. Each of these components is described in subsequent pages of the chapter:
- VPC networking components
- Elastic Network Interface (ENI)
