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.

Network APIs

As the ways we build, deploy, and operate networks evolve, new protocols and interfaces are emerging to ease machine-to-machine communication—a primary enabler of network automation. In this and the following chapters, we’ll navigate through some of these new capabilities and explore how to take advantage of them in the context of the Go programming language.

The network Command-Line Interface (CLI) is what we, network engineers, have used for decades to operate and manage network devices. As we move toward a more programmatic approach to managing networks, simply relying on faster CLI command execution might not be enough to deploy network automation solutions at scale.

Solutions that don’t have a strong foundation are brittle and unstable. Hence, when possible, we prefer to build network automation projects based on structured data and machine-friendly Application Programming Interfaces (APIs). The target use case for these interfaces isn&...
