Step-by-step instruction on writing your first production-ready servers with Golang.

Google's Go language, otherwise known as Golang, is a fast, simple, and reliable language that is rapidly becoming a highly popular choice for developers of all kinds. With particular utility in cloud-native environments, Golang is being adopted in major projects like Docker and Ethereum thanks to its user-friendly features, like concurrency and easy deployment.

In Practical Golang: Building Scalable Network and Non-Network Applications, expert coder and devops engineer Amit Saha delivers a step-by-step guide to writing production-ready HTTP 1.1, HTTP2, RPC, and TCP/UDP servers. Walking you through the entire process of learning this already straightforward language, from your first application to your first deployed server, the authors rely solely on the most popular open-source projects to ensure you can apply the book's advice in any cloud environment.

My goal in this book is to showcase the various features of the Go language and the standard libraries (along with a few community-maintained packages) by developing various categories of applications. Once you have refreshed or learned the language fundamentals, this book will help you take the next step. I have adopted a writing style where the focus is on using various features of the language and its libraries to solve the particular problem at hand—one that you care about.

You will not find a detailed walk-through of a language feature or every feature of a certain package. You will learn just enough to build a command-line tool, a web application, or a gRPC application. I focus on a strictly chosen subset of the fundamental building blocks for such applications to provide a compact and actionable guide. Hence, you may find that the book doesn't cover the more higher-level use cases that you may want to learn about. That is intentional, as the implementation of those higher-level use cases is often dependent on domain-specific software packages, and hence no single book can do justice to recommending one without missing out on another. I also strive to use standard library packages as far as possible for writing the applications in the book. This is again done to ensure that the learning experience is not diluted. Nonetheless, I hope that the building blocks you learn about in the book will provide you with a solid foundation to leverage higher-level libraries to build your applications.

In this book, you'll get:

Fulsome descriptions of best practices on load balancing, scaling, and failure handling
Stepwise guidance on writing an HTTP service from scratch using only Golang's standard library
Easy tutorials on implementing RPC and HTTP interfaces for RPC services
Straightforward instructions on using SQL databases

Perfect for software developers, devops engineers, and other programming professionals, Practical Golang is also an indispensable resource for anyone who wants to go beyond the basics of Golang and deploy robust and practical servers.
