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.

Creating and trusting a self-signed certificate

There are many different ways of creating TLS certificates for your web application. But regardless of the method you use, the principles remain the same.

For gRPC, all the principles of applying a certificate are identical to those for an ordinary web application that is accessible via HTTP/1.1. We even use the same kind of file to encrypt communication between the endpoints.

However, in an ASP.NET application, the application of the certificate differs depending on the kind of server you want to host your application on. Applying a certificate on IIS would be different from applying one on Kestrel. But even on the same type of server, there are still different ways to apply a certificate. For example, just like the HTTP port mappings we covered in the previous section, you can reference the certificate directly in the code, or you can reference it in the application settings.

Covering all of the different ways of applying certificates...
