Hands-On RESTful Web Services with Go - Second Edition

By: Naren Yellavula

Overview of this book

Building RESTful web services can be tough as there are countless standards and ways to develop API. In modern architectures such as microservices, RESTful APIs are common in communication, making idiomatic and scalable API development crucial. This book covers basic through to advanced API development concepts and supporting tools. You’ll start with an introduction to REST API development before moving on to building the essential blocks for working with Go. You’ll explore routers, middleware, and available open source web development solutions in Go to create robust APIs, and understand the application and database layers to build RESTful web services. You’ll learn various data formats like protocol buffers and JSON, and understand how to serve them over HTTP and gRPC. After covering advanced topics such as asynchronous API design and GraphQL for building scalable web services, you’ll discover how microservices can benefit from REST. You’ll also explore packaging artifacts in the form of containers and understand how to set up an ideal deployment ecosystem for web services. Finally, you’ll cover the provisioning of infrastructure using infrastructure as code (IaC) and secure your REST API. By the end of the book, you’ll have intermediate knowledge of web service development and be able to apply the skills you’ve learned in a practical way.

Scaling our REST API Using Microservices

Building a REST API is easy in terms of the concept. But scaling it to accept huge traffic is a challenge. Till now, we've looked into the details of creating REST API structures and sample REST APIs. In this chapter, we are going to explore Go Micro, a wonderful, idiomatic Go package for building microservices.

This is the age of microservices, where huge applications are commonly broken down into loosely coupled components. The microservice architecture allows companies to quickly iterate in parallel. We will start by defining the term microservices, and then move on to Go Micro by creating Remote Procedure Call (RPC)-/REST-style microservices.

In this chapter, we will cover the following topics:

  • What are microservices?
  • Monoliths versus microservices
  • Introducing Go Micro, a package for building microservices
  • Adding logging to the...
