In Chapter 4, Networking on AWS, we discussed networking on AWS, which laid the foundation for being able to create our own VPCs. We discussed IP addressing, subnets, and route tables. In this chapter, we will learn several methods to build, secure, and connect to a VPC. First, we're going to look at classic EC2s, which are instances that are launched outside of a VPC. Then, we'll talk about the VPC that AWS already creates for you, the default VPC. Next, we'll demonstrate creating a VPC, using the VPC Wizard, and then creating one from scratch. After that, we'll talk about several ways to connect to the instances in your VPC, and then we'll make your VPCs more secure by introducing network access control lists and Bastion instances.
Finally, we'll discuss making your architectures highly available by leveraging multiple availability...
