Mastering Python Networking - Fourth 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, Fourth edition, you'll embark on a Python-based journey to transition from a traditional network engineer to a network developer ready for the next generation of networks. This new edition is completely revised and updated to work with the latest Python features and DevOps frameworks. In addition to new chapters on introducing Docker containers and Python 3 Async IO for network engineers, 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 AWS and Azure cloud networking. You will use Git for code management, GitLab for continuous integration, and Python-based testing tools to verify your network.

Azure Global Infrastructure

Similar to AWS, an Azure global infrastructure consists of regions, Availability Zones (AZs), and edge locations. At the time of writing, Azure has 60+ regions and more than 200+ physical datacenters, as illustrated on the product page (https://azure.microsoft.com/en-us/global-infrastructure/):

Like AWS, Azure products are offered via regions, so we need to check service availability and pricing based on regions. We can also build redundancy into the service by building the service in multiple AZs. However, unlike AWS, not all Azure regions have AZs, and not all Azure products support them. In fact, Azure did not announce the general availability of AZs until 2018, and they are only offered in select regions.

This is something to be aware of when picking our region. I recommend picking regions with AZs such as West US 2, Central US...
