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.

Epilogue

Networking Primer

Communication over networks is at the core of all of our modern technology and gRPC is one of the high-level frameworks that we can use to achieve efficient reception and transmission of data. As it is high level, it gives you abstractions for sending and receiving data without thinking about all the things that could go wrong when communicating over the wire. In this chapter, the goal is to understand, at a lower level (not the lowest), what happens when we send/receive messages in gRPC Go. This will help you get a sense of what’s going on and, later on, when we talk about debugging and observability, you’ll be able to grasp the concepts presented more easily.

In this chapter, we’re going to cover the following main topics:

  • HTTP/2
  • RPC operations
  • RPC types
  • The life cycle of an RPC
