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.

Virtual private cloud

Amazon Virtual Private Cloud (Amazon VPC) enables customers to launch AWS resources into a virtual network dedicated to the customer's account. It is truly a customizable network that allows you to define your own IP address range, add and delete subnets, create routes, add VPN gateways, associate security policies, connect EC2 instances to your own datacenter, and much more. In the early days when VPC was not available, all EC2 instances in the AZ were on a single, flat network that was shared among all customers. How comfortable would the customer be with putting their information in the cloud? Not very, I'd imagine. Between the launch of EC2 in 2007 until the launch of VPC in 2009, VPC functions was one of the most requested features of AWS.

The packets leaving your EC2 host in a VPC are intercepted by the Hypervisor. The Hypervisor will check...
