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. What is the equivalent of the fixed64 data type in C#?
    1. long
    2. ulong
    3. int
    4. uint
  2. What is the difference between int32 and fixed32?
    1. The int32 data type will have only as many bytes allocated as necessary, while fixed32 always occupies 4 bytes.
    2. There is no difference. Two data types exist purely for backward compatibility.
    3. The int32 data type only accepts positive numbers, while fixed32 accepts negative numbers.
    4. The int32 data type accepts only whole numbers, while fixed32 accepts decimal point numbers.
  3. How do you create a multi-dimensional array in Protobuf?
    1. Apply the repeated repeated keyword to the field.
    2. There is no way of creating anything that resembles a multi-dimensional array in Protobuf.
    3. Create a repeated field of a message that itself has a repeated field.
    4. You can only do it if you apply a custom option.
  4. What happens if you assign a value on a field within a oneof block if another field has already been set?
    1. A compiler error is thrown.
    2. The original field gets unset...
