Amazon Web Services (Web) has a huge global infrastructure, with millions of resources used by customers all over the world. As you’re building and deploying your own applications, how do you ensure that your resources are isolated from everything else out there?
An Amazon Virtual Private Cloud (VPC) is effectively your own private network within AWS. This is what separates your resources from everything else. In this video, I’ll provide an overview of networking basics in AWS (VPC, subnets, internet gateway), dig into some detail about CIDR notation and how IP addressing works within a VPC, and wrap up with a brief discussion of network access control lists (ACLs) and security groups.
