Overview of this book

Go is the language of the Internet age, and the latest version of Go comes with major architectural changes. Implementation of the language, runtime, and libraries has changed significantly. The compiler and runtime are now written entirely in Go. The garbage collector is now concurrent and provides dramatically lower pause times by running in parallel with other Go routines when possible. This book will show you how to leverage all the latest features and much more. This book shows you how to build powerful systems and drops you into real-world situations. You will learn to develop high quality command-line tools that utilize the powerful shell capabilities and perform well using Go's in-built concurrency mechanisms. Scale, performance, and high availability lie at the heart of our projects, and the lessons learned throughout this book will arm you with everything you need to build world-class solutions. You will get a feel for app deployment using Docker and Google App Engine. Each project could form the basis of a start-up, which means they are directly applicable to modern software markets.

Solution design

We will start by listing some high-level acceptance criteria for our solution and the approach we want to take:

  • The solution should create a snapshot of our files at regular intervals as we make changes to our source code projects

  • We want to control the interval at which the directories are checked for changes

  • Code projects are primarily text-based, so zipping the directories to generate archives will save a lot of space

  • We will build this project quickly, while keeping a close watch over where we might want to make improvements later

  • Any implementation decisions we make should be easily modified if we decide to change our implementation in the future

  • We will build two command-line tools: the backend daemon that does the work and a user interaction utility that will let us list, add, and remove paths from the backup service

The project structure

It is common in Go solutions to have, in a single project, both a package that allows other Go programmers to use your capabilities and...
