Mastering Python Networking - Third 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 Mastering Python Networking, Third edition, 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 new edition is completely revised and updated to work with Python 3. In addition to new chapters on network data analysis with ELK stack (Elasticsearch, Logstash, Kibana, and Beats) and Azure Cloud Networking, it includes updates on using newer libraries such as pyATS and Nornir, as well as Ansible 2.8. Each chapter is updated with the latest libraries with working examples to ensure compatibility and understanding of the concepts. Starting with a basic overview of Python, the book teaches you how it can interact with both legacy and API-enabled network devices. You will learn to leverage high-level Python packages and frameworks to perform network automation tasks, monitoring, management, and enhanced network security followed by Azure and AWS Cloud networking. Finally, you will use Jenkins for continuous integration as well as testing tools to verify your network.

AWS setup

If you do not already have an AWS account and wish to follow along with these examples, please log on to and sign up. The process is pretty straightforward and simple; you will need a credit card and some way to verify your identity, such as a mobile phone that can accept text messages.

A good thing about AWS when we are just getting started is that they offer a number of services in a free tier (, where you can use the services for free up to a certain level. For example, we will be using the Elastic Compute Cloud (EC2) service in this chapter; the free tier for EC2 is the first 750 hours per month for its t2.micro instance for the first 12 months.

I recommend always starting with the free tier and gradually increasing your tier when the need arises. Please check the AWS site for the latest offerings:
