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.

John Doak is a Principal Software Engineer Manager at Microsoft, an ex-Google Network Systems Engineer (SRE), and an ex-LucasArts/Lucasfilm Network Engineer.

I cut my teeth in networking at LucasArts after I asked the Director of IT what my next career step was. He made me a network engineer on the spot and said to go buy a Cisco book and configure a router for a new T1 we just got. There is nothing quite like staring at a box in a closet, hoping that the Cisco book you have placed on top of your head will give you knowledge via osmosis. I spent the next several years there automating my way out of doing work (portals that reset network MAC security parameters, moved ports to new VLANs, auto-balanced inbound BGP traffic using route maps, and so on).

I moved from there to Google, where I spent the bulk of my time automating the vendor backbone known as Backend Backbone (B2). I wrote the first autonomous services that programmed the various routers. Then, I built the...
