With "Mastering Python Network Automation," you can streamline container orchestration, configuration management, and resilient networking with Python and its libraries, allowing you to emerge as a skilled network engineer or a strong DevOps professional.

From the ground up, this guide walks readers through setting up a network automation lab using the NS3 network simulator and Python programming. This includes the installation of NS3, as well as python libraries like nornir, paramiko, netmiko, and PyEZ, as well as the configuration of ports, hosts, and servers. This book will teach you the skills to become a proficient automation developer who can test and fix any bugs in automation scripts. This book examines the emergence of the service mesh as a solution to the problems associated with service-to-service communication over time.

"Mastering Shell for DevOps" is all about giving DevOps, cloud, and Linux folks the know-how to automate and make their workflows more efficient with shell scripting. The book uses real-world examples and simple instructions to show how to automate tasks and move away from manual work in a DevOps environment. We start with the basics of shell scripting, so you can learn to write scripts that get the job done. It then moves on to version control with Git and GitHub, showing the importance of collaboration and code management in this context. The book then jumps into infrastructure provisioning and configuration management, showing you how to automate the setup of servers and services using tools like AWS CLI, Docker, and Kubernetes. As your skills grow, you'll learn to set up monitoring and logging tools, automate incident detection and resolution, and manage network traffic and load balancing. The book also helps you learn how to automate security tasks, including user access management, vulnerability scanning, patching, and compliance checks. By the end of the book, you'll have a whole toolkit of shell scripts that will help you work more efficiently, reliably, and securely in your DevOps practices.

Key Features

• Get your infrastructure provisioning done automatically with shell scripts for reliable, fast deployments.
• Make version control a lot easier by using Git and shell scripting for collaborative development.
• Set up a system to monitor and log your data automatically so you can spot any issues early on.
• Make it easy to spot and fix problems so your system stays up and running.
• Get the most out of your network traffic and load balancing with shell scripts for top performance.
• You can deploy and manage containers with Docker, Podman, and Kubernetes using automation.
• Give security a boost with scripted access management and permission assignments.
• Automate vulnerability scanning and patching to keep your system secure.
• Run system audits and compliance checks with scripted automation.

If you're a developer getting into networking for the first time or an IT pro looking to build practical automation skills, this second edition gives you a clear and structured path to master essential networking concepts and become a confident, hands-on Python network administrator. If you're looking to automate repetitive networking tasks, build tools for infrastructure, or become a network administrator, you'll find this book teaching all the skills, structure, and mindset to make it happen.

You'll start off by getting the basics of Python down and then quickly move on to TCP, UDP, and socket programming. You'll work with protocols like HTTP, FTP, DNS, and email, and you'll use Python to automate everyday network tasks. As you read on, you'll dive into modern network automation using Netmiko, Paramiko, and NAPALM, manage asynchronous tasks with AsyncIO, and set up monitoring and analysis workflows through SNMP, ping3, iperf3, and Locust. You'll also use SimPy to simulate networks, program firewalls, scanning, encryption, and VPNs. You'll also get to work on configuration management and orchestration using Ansible. This will teach you how to automate server and network setups, manage software lifecycles, enforce standards, and integrate Python for advanced logic.

This book is all about clarity and practicality, using simple, easy-to-follow examples that work in the real world. It's not meant to deal with complicated business scenarios, but it does cover the most important, routine and common jobs of network programming.

Key Features

• Learn the basics of Python syntax and data structures for network automation.
• Get the hang of TCP, UDP, and socket programming for real communication tasks.
• Practice your skills with HTTP, FTP, DNS, and email protocols using real-world Python scripts.
• Set up SSH connections and device configurations using Netmiko, Paramiko, and NAPALM.
• Take charge of asynchronous network operations with Python's AsyncIO library.
• Keep an eye on, look at, and test networks using SNMP, ping3, iperf3, Locust, and SimPy.
• Make your network security stronger by using firewalls, scanning, SSL/TLS, and VPN configurations.
• Take advantage of the NAPALM and Git integration to automate your configuration management and version control.
• With Ansible playbooks, roles, and automation workflows, you can orchestrate server and network setups.
