Implement, test, and deploy production-grade microservices

What is this book about?

In recent years, the popularity of microservice architecture has surged, bringing forth a new set of requirements. Among these, efficient communication between 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 debug your API endpoints. Finally, you’ll get to grips with deploying application services via Docker images and Kubernetes.

This book covers the following exciting features:

Understand the different API endpoints that gRPC lets you write
Discover the essential considerations when writing your Protobuf files
Compile Protobuf code with protoc, Buf, and Bazel for efficient development
Gain insights into how advanced gRPC concepts work
Grasp techniques for unit testing and load testing your API
Get to grips with deploying your microservices with Docker and Kubernetes
Discover tools to write secure and efficient gRPC code

Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

message AddTaskRequest {
     string description = 1;
     google.protobuf.Timestamp due_date = 2;
}

Following is what you need for this book: Whether you’re interested in microservices or looking to use gRPC in your product, this book is for you. To fully benefit from its contents, you’ll need a solid grasp of Go programming and using a terminal. If you’re already familiar with gRPC, this book will help you to explore the different concepts and tools in depth.
