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.
Table of Contents (13 chapters)


  1. What is one of the reasons Protobuf is the default data format for gRPC?
    1. The serialized data is human-readable
    2. It is dynamically typed
    3. It is type-safe
  2. In the Go implementation, which component generates server/client code?
    1. Protoc
    2. The gRPC Go plugin
    3. Other
  3. What are service descriptors in the context of gRPC-generated code?
    1. They describe which endpoints a service has and how to handle requests
    2. They describe how to return responses
    3. Both of these
  4. How will the user code be able to implement the logout endpoint?
    1. By writing code in the generated Logout function
    2. By creating a copy of the generated code and editing it
    3. By using type embedding with the generated server and implementing Logout for that type
