Network Automation with Go

By: Nicolas Leiva, Michael Kashin

Overview of this book

Go’s built-in first-class concurrency mechanisms make it an ideal choice for long-lived low-bandwidth I/O operations, which are typical requirements of network automation and network operations applications. This book provides a quick overview of Go and hands-on examples within it to help you become proficient with Go for network automation. It’s a practical guide that will teach you how to automate common network operations and build systems using Go. The first part takes you through a general overview, use cases, strengths, and inherent weaknesses of Go to prepare you for a deeper dive into network automation, which is heavily reliant on understanding this programming language. You’ll explore the common network automation areas and challenges, what language features you can use in each of those areas, and the common software tools and packages. To help deepen your understanding, you’ll also work through real-world network automation problems and apply hands-on solutions to them. By the end of this book, you’ll be well-versed with Go and have a solid grasp on network automation.

What is network automation?

As a relatively new discipline, it’s not uncommon to see a broad spectrum of network automation definitions that vary in scope and goals. Network automation isn’t about one use case or technology in particular, but rather what can be of help in your environment and benefit your business.

Some engineers would argue that routing protocols already automate networks and the CLI is the intent-based API, transforming individual network commands into a dynamic network state. We don’t try to argue with this point of view, as there are some grains of truth in these statements, but it’s certainly not the most popular definition in the industry.

Instead, let’s define network automation as a set of processes to automate common manual workflows performed by a network operator, such as provisioning services, performing software upgrades, or telemetry processing. This includes tasks that network engineers would otherwise traditionally...
