Summary
In this chapter, you reviewed the foundational networking component of the AWS cloud, the VPC. You learned how to create a VPC network using a CloudFormation template with both a public and private subnet and then attach an IGW for internet connectivity. After creation, you explored the different components of the VPC to become familiar with them.
You then reviewed the different network connectivity options available for the VPCs in the account you are working on as well as other accounts and then the network traffic back to data centers that need to connect to AWS resources. These included options for connecting over public networks, such as VPNs to keep your transmissions secure and encrypted, along with Direct Connect, peering, and endpoints to keep your transmissions off the public internet.
Chapter 11, Securing EC2 Instances, will discuss how to secure EC2 instances when you are inside the perimeter of your network.
