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 Go?

During the second half of 2007, Robert Griesemer, Rob Pike, and Ken Thompson started discussing the design of a new programming language that would solve some problems they were experiencing when writing software at Google, such as the increased complexity to use some languages, long code compilation times, and not being able to program efficiently on multiprocessor computers.

Rob Pike was trying to take some concurrency and communicating channels ideas into C++, based on his earlier work on the Newsqueak language in 1988, as he describes in Go: Ten years and climbing (Further reading) and Less is exponentially more (Further reading). This turned out to be too hard to implement. He would work out of the same office with Robert Griesemer and Ken Thompson. Ken had worked together with Rob Pike in the past to create the character-encoding UTF-8, while Ken Thompson had designed and implemented the Unix operating system and invented the B programming language (the predecessor to...
