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.

Summary


We covered a lot through this chapter as we put together a real example of a micro-service. There is a lot of work involved without code generation, but the benefits for large teams and big micro-service architectures pay for the investment as you build self-similar, discrete components that make up the system.

We learned how gRPC and protocol buffers give us highly efficient transport communications between clients and servers. Using the proto3 language, we defined our service, including messages, and used the tools to generate a Go package that provided the client and server code for us.

We explored the fundamentals of Go kit and how we can use endpoints to describe the methods of our services. We let Go kit do the heavy lifting for us when it came to building HTTP and gRPC servers by making use of the packages included in the project. We saw how middleware functions let us easily adapt our endpoints to, among other things, rate limit the amount of traffic the server will have to...
