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.

In this chapter, we looked at AWS cloud networking services. We went over the AWS network definitions of Region, Availability Zone, edge locations, and Transit Center. By understanding the overall AWS network, this gives us a good idea of some of the limitations and constraints of the other AWS network services. Throughout this chapter, we used the AWS CLI, the Python Boto3 library, as well as CloudFormation to automate some of the tasks.

We covered AWS Virtual Private Cloud in depth, with the configuration of the route table and route targets. The example on security groups and network ACLs took care of the security for our VPC. We also looked at EIPs and NAT gateways in relation to allowing external access.

There are two ways to connect AWS VPC to on-premise networks: Direct Connect and IPSec VPN. We briefly looked at each and the advantages of using them. Toward the end of this chapter, we looked at network scaling services offered by AWS, including...
