Mastering Python Networking - Second Edition

By: Eric Chou

Overview of this book

Networks in your infrastructure set the foundation for how your application can be deployed, maintained, and serviced. Python is the ideal language for network engineers to explore tools that were previously available to systems engineers and application developers. In this second edition of Mastering Python Networking, you’ll embark on a Python-based journey to transition from traditional network engineers to network developers ready for the next-generation of networks. This book begins by reviewing the basics of Python and teaches you how Python can interact with both legacy and API-enabled network devices. As you make your way through the chapters, you will then learn to leverage high-level Python packages and frameworks to perform network engineering tasks for automation, monitoring, management, and enhanced security. In the concluding chapters, you will use Jenkins for continuous network integration as well as testing tools to verify your network. By the end of this book, you will be able to perform all networking tasks with ease using Python.

Direct Connect and VPN

Up to this point, our VPC is a self-contained network that resides in the AWS network. It is flexible and functional, but to access the resources inside of the VPC, we will need to access them with their internet-facing services such as SSH and HTTPS.

In this section, we will look at the two ways AWS allow us to connect to the VPC from our private network: IPSec VPN Gateway and Direct Connect.

VPN Gateway

The first way to connect our on-premise network to VPC is with traditional IPSec VPN connections. We will need a publicly accessible device that can establish VPN connections to AWS's VPN device. The customer gateway needs to support route-based IPSec VPNs where the VPN connection is treated...
