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.

In this chapter, I will be using Wireshark ( to analyze a gRPC call and get the necessary captures that illustrate the different concepts presented. As this is still early in this book, I do not expect you to reproduce all of this. However, if you plan to do a little bit more digging, you can install Wireshark and open the capture files provided in the Git repository ( under the chapter1 directory.

To display these capture files, you can simply import them into Wireshark and apply a display filter to them. As we are interested specifically in HTTP/2 and gRPC payloads, and I was using port 50051 for communication, you can use the following filter: tcp.port == 50051 and (grpc or http2).
