Microservices Communication in .NET Using gRPC

By: Fiodar Sazanavets

Overview of this book

Explore gRPC's capabilities for faster communication between your microservices using the HTTP/2 protocol in this practical guide that shows you how to implement gRPC on the .NET platform. gRPC is one of the most efficient protocols for communication between microservices that is also relatively easy to implement. However, its official documentation is often fragmented and.NET developers might find it difficult to recognize the best way to map between C# data types and fields in gRPC messages. This book will address these concerns and much more. Starting with the fundamentals of gRPC, you'll discover how to use it inside .NET apps. You’ll explore best practices for performance and focus on scaling a gRPC app. Once you're familiar with the inner workings of the different call types that gRPC supports, you'll advance to learning how to secure your gRPC endpoints by applying authentication and authorization. With detailed explanations, this gRPC .NET book will show you how the Protobuf protocol allows you to send messages efficiently by including only the necessary data. You'll never get confused again while translating between C# data types and the ones available in Protobuf. By the end of the book, you’ll have gained practical gRPC knowledge and be able to use it in .NET apps to enable direct communication between microservices.

Chapter 2: When gRPC Is the Best Tool and When It Isn't

In this chapter, we will cover use cases for Google Remote Procedure Call (gRPC). We will use sample applications to demonstrate why gRPC is a great tool to be used in some scenarios but isn't the best one for other scenarios.

The main objective of this chapter is to demonstrate how convenient it is to use gRPC for microservices architecture and asynchronous communication, but you will also be shown how inconvenient it is to use gRPC in a browser or on any platform that doesn't support the HyperText Transfer Protocol 2 (HTTP/2) protocol. You will also be shown alternative technologies you can use when gRPC is not the best answer.

We will cover the following topics in this chapter:

  • Why gRPC is a great tool for microservices
  • How gRPC can be a good tool for asynchronous communication
  • Why gRPC is not the best tool for browsers
  • Where SignalR would beat gRPC
