AWS VPCs
As we now have a basic understanding of what a computer network is, let us understand what an AWS VPC is. A VPC is similar to a computer network that we can create in an on-premises data center. 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.
