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.

Questions

  1. Can gRPC support asynchronous calls?
    1. No, it only supports synchronous calls.
    2. Yes, by utilizing streaming.
    3. Yes, but only by using async/await on the client.
    4. Yes, but only on gRPC-Web.
  2. Can you use gRPC inside a browser?
    1. Not at all.
    2. Yes, it just works out of the box.
    3. Yes, but only via gRPC-Web.
    4. Yes, but it only works with a Blazor client.
  3. Which one of the following is NOT a limitation of gRPC-Web?
    1. Server-streaming calls
    2. Client-streaming calls
    3. Having to convert messages to HTTP/1.1
    4. Having to use a proxy
  4. Do you need to make additional modifications to enable gRPC-Web if you already have gRPC enabled?
    1. No, the framework will automatically convert gRPC to gRPC-Web.
    2. Yes, both on the server and the client.
    3. Yes, but only on the client.
    4. Yes, but only on the server.
  5. What can SignalR do that gRPC can't?
    1. Bi-directional streaming
    2. Client-streaming calls
    3. Asynchronous calls
    4. Calls from the server to the client without a request from the client
