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.

There are many infrastructure automation frameworks besides Ansible—namely Chef, Puppet, and SaltStack. Each framework offers its own unique features and models; there is no one right framework that fits all organizations. In this section, I would like to list some of the advantages of Ansible over other frameworks and why I think this is a good tool for network automation.

I will list the advantages of Ansible without comparing them to other frameworks. Other frameworks might adopt some of the same philosophies or certain aspects of Ansible, but rarely do they contain all of the features that I will be mentioning. I believe it is the combination of all the following features and philosophy that makes Ansible ideal for network automation.


Unlike some of its peers, Ansible does not require a strict master-client model. No software or agent needs to be installed on the client that communicates back to the server. Outside...
