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.

Chapter 9.  Building a Q&A Application for Google App Engine

Google App Engine gives developers a NoOps (short for No Operations, indicating that developers and engineers have no work to do in order to have their code running and available) way of deploying their applications, and Go has been officially supported as a language option for some years now. Google's architecture runs some of the biggest applications in the world, such as Google Search, Google Maps, and Gmail, among others, so is a pretty safe bet when it comes to deploying our own code.

Google App Engine allows you to write a Go application, add a few special configuration files, and deploy it to Google's servers, where it will be hosted and made available in a highly available, scalable, and elastic environment. Instances will automatically spin up to meet demand and tear down gracefully when they are no longer needed with a healthy free quota and preapproved budgets.

Along with running application instances, Google App...
