Network engineers are finding it harder than ever to rely solely on manual processes to get their jobs done. New protocols, technologies, delivery models, and the need for businesses to become more agile and flexible have made network automation essential. The updated second edition of this practical guide shows network engineers how to use a range of technologies and tools, including Linux, Python, APIs, and Git, to automate systems through code. This edition also includes brand new topics such as network development environments, cloud, programming with Go, and a reference network automation architecture.Network Programmability and Automation will help you automate tasks involved in configuring, managing, and operating network equipment, topologies, services, and connectivity. Through the course of the book, you'll learn the basic skills and tools you need to make this critical transition.You'll learn:Programming skills with Python and Go: data types, conditionals, loops, functions, and moreHow to work with Linux-based systems, the foundation for modern networking and cloud platformsData formats and models: JSON, XML, YAML, and YANGJinja templating for creating network device configurationsThe role of application programming interfaces (APIs) in network automationSource control with Git to manage code changes during the automation processCloud-native technologies like Docker and KubernetesHow to automate network devices and services using Ansible, Salt, and TerraformTools and technologies for developing and continuously integrating network automation

Learn how to use modern monitoring tools for building network observability solutions that enhance operations and promote an effective automation strategy, with step-by-step guidance and practical examples Key FeaturesCraft a dynamic observability stack with real-world, practical applicationsBuild intuitive dashboards and alerts by collecting and normalizing diverse network dataLeverage observability data to strengthen automation strategies for network operationsPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionAs modern IT services and software architectures such as microservices rely increasingly on network performance, the relevance of networks has never been greater. Network observability has emerged as a critical evolution of traditional monitoring, providing the deep visibility needed to manage today’s complex, dynamic environments. In Modern Network Observability, authors David Flores, Christian Adell, and Josh VanDeraa share their extensive experience to guide you through building and deploying a flexible observability stack using open-source tools.This book begins by addressing the limitations of monolithic monitoring solutions, showing you how to transform them into a composable, flexible observability stack. Through practical implementations, you’ll learn how to collect, normalize, and analyze network data from diverse sources, build intuitive dashboards, and set up actionable alerts that help you stay ahead of potential issues. Later, you’ll cover advanced topics, such as integrating observability data into your network automation strategy, ensuring your network operations align with business objectives.By the end of this book, you'll be able to proactively manage your network, minimize downtime, and ensure resilient, efficient, and future-proof operations.What you will learnCollect and normalize data from various sources using Telegraf and LogstashEnrich operational data with crucial context from a Source of Truth such as NautobotVisualize data and create insightful dashboards with GrafanaAutomate alerts and responses for your network operations strategy using PrefectUnderstand when to build or buy an observability stack, with tips and best practicesExplore practical machine learning techniques to enhance observability data valueWho this book is forThis book is for all network engineering roles such as network analysts, administrators, architects, security personnel, support staff, and managers working in both on-premises and cloud environments who are tasked with implementing or using network monitoring solutions. Basic programming knowledge in Python and Go, familiarity with networking concepts, and a fundamental understanding of Docker containers for lab scenarios will be required.

Explore network automation with Ansible by configuring network infrastructure fast, reliably, and repeatedly, all while creating a lab utilizing open and available network operating systems and toolsKey FeaturesDesign, build, and automate network devices and cloud networking resources using AnsibleOrchestrate workflows with AWX and integrate Nautobot as a Source of TruthStart with Event-Driven Ansible and manage Terraform workflows seamlesslyPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionNetwork Automation Cookbook, now in its second edition, is your essential guide to building robust network automation workflows across modern hybrid infrastructures. Building on the foundation laid in the first edition, this version dives deeper into Ansible’s role in automating network infrastructure, expanding coverage to include modern use cases across enterprise and cloud networks.The book introduces Ansible’s core concepts, such as playbooks, inventories, variables, loops, and templates, and progresses to advanced topics such as parallelism, fact caching, custom filters, and modular design. You will automate real-world scenarios using Nokia SR, Cisco IOS, Juniper, and Arista devices in a fully reproducible virtual lab. The chapters also help you explore cloud automation for AWS, Azure, and Google Cloud, and integrate validation tools such as PyATS, Batfish, and Nautobot. New chapters cover event-driven automation, AWX for workflow execution, and Terraform integration. By using hands-on labs and fully reproducible recipes, you can practice real-world scenarios and reinforce your skills.By the end of this book, you’ll be well-equipped with the tools and workflows to automate infrastructure efficiently with Ansible.What you will learnBuild Ansible playbooks, roles, and inventories from scratchAutomate Juniper and Arista network devicesDeploy cloud networks on AWS, Azure, and Google CloudValidate networks with Batfish and NAPALMUse AWX for workflow automation and job schedulingIntegrate Nautobot as a dynamic inventory sourceRun all recipes in containerized, hardware-free labsApply event-driven automation using Ansible RulebooksWho this book is forThis second edition will help network engineers, DevOps pros, cloud architects, automation engineers, and NREs understand Ansible’s role in network automation and how it integrates with tools like Terraform and event-driven architectures. The book requires basic networking knowledge and familiarity with YAML to maximize learning.
