gRPC Go for Professionals

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.

Another crucial step of production-grade APIs is deploying the services online. In this section, we will see how we can create a Docker image for gRPC Go, deploy it to Kubernetes, and finally deploy the Envoy proxy to let clients make requests from outside the cluster to a server inside it.


This first step in deploying is often containerizing your application with Docker. If we did not do so, we would have to deal with errors depending on the server architecture, tools not being available on it, and so on. By containerizing our application, we can build our image once and run it everywhere where Docker is available.

We are going to focus on containerizing our server. This makes much more sense than working on the client because we will later deploy our gRPC server as microservices in Kubernetes and we will make the client, which is outside, make requests to them.

The first thing that we can think about is what all the steps needed to build our application...
