In this chapter, we looked at AWS Cloud Networking services. We went over the AWS network definitions of Region, Availability Zone, Edge Locations, and Transit Center. By understanding the overall AWS network, this gives us a good idea of some of the limitations and contains for the other AWS network services. Throughout this chapter, we used the AWS CLI, the Python Boto3 library, as well as CloudFormation to automate some of the tasks. 

We covered the AWS virtual private cloud in depth with the configuration of the route table and route targets. The example on security groups and network ACL controls the security for our VPC. We also looked at Elastic IP and NAT Gateways regarding allowing external access. 

There are two ways to connect AWS VPC to on-premise networks: Direct Connect and IPSec VPN. We briefly looked at each and the advantages of using them. Toward the end of this chapter, we looked at network scaling services offered by AWS, including Elastic Load Balancing, Route53 DNS, and CloudFront. 

In Chapter 10, Working with Git, we will take a more in-depth look at the version control system we have been working with: Git.
