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.

Azure VPNs

As the network continues to grow, there might come a time when we need to connect the Azure VNet to our on-premise location. A VPN gateway is a type of VNet gateway that can encrypt the traffic between a VNet and our on-premise network and remote clients. Each VNet can only have one VPN gateway, but multiple connections can be built on the same VPN gateway.

More information about Azure VPN gateways can be found at this link https://docs.microsoft.com/en-us/azure/vpn-gateway/.

VPN gateways are actually virtual machines themselves, configured with encryption and routing services, but cannot be directly configured by the user. Azure provides a list of SKUs based on the type of tunnel, number of concurrent connections, and total throughput (https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpn-gateway-settings#gwsku):
