gRPC Go for Professionals

By: Clément Jean

Overview of this book

In recent years, the popularity of microservice architecture has surged, bringing forth a new set of requirements. Among these, efficient communication between the different services takes center stage, and that's where gRPC shines. This book will take you through creating gRPC servers and clients in an efficient, secure, and scalable way. However, communication is just one aspect of microservices, so this book goes beyond that to show you how to deploy your application on Kubernetes and configure other tools that are needed for making your application more resilient. With these tools at your disposal, you’ll be ready to get started with using gRPC in a microservice architecture. In gRPC Go for Professionals, you'll explore core concepts such as message transmission and the role of Protobuf in serialization and deserialization. Through a step-by-step implementation of a TODO list API, you’ll see the different features of gRPC in action. You’ll then learn different approaches for testing your services and debugging your API endpoints. Finally, you’ll get to grips with deploying the application services via Docker images and Kubernetes.

A mature technology

gRPC is not just another new cool framework that you can disregard as being a fad It is a framework that has been battle-tested at scale for over a decade by Google. Originally, the project was for internal use, but in 2016, Google decided to provide an open source version of it that was not tied to the specifics of the company’s internal tooling and architecture.

After that, companies such as Uber—and a lot more—migrated their existing services to gRPC for efficiency but also for all the extra features that it offers. Moreover, some open projects such as etcd, which is a distributed key-value store used at the core of Kubernetes, use gRPC for communication across multiple instances.

Recently, Microsoft joined the effort around building a .NET implementation of gRPC. While it is not the goal of this book to explain what it did, it clearly shows an interest in the project. Furthermore, the more that companies such as this are willing to...
