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.

Summary

Configuration generation, deployment, reporting, and compliance remain the most popular network automation operations. This is where the immediate benefits of introducing automation are greatest and most visible, making it the first logical step into the world of automation and DevOps. Configuration management is one of those repetitive tasks network engineers spend most of their time on, so it’s a natural fit for automation. But sending a new configuration to a device is just part of a broader process that should consider failure handling, from syntax errors in the configuration to how to recover properly if the connection to a remote device drops. In this context, you can abstract some repetitive tasks with reusable code that offers generic functionality to reduce the time and effort to automate your use cases. This is what automation frameworks offer, which we will discuss in the next chapter.
