Practical Microservices with Dapr and .NET - Second Edition

By: Davide Bedin

Overview of this book

This second edition will help you get to grips with microservice architectures and how to manage application complexities with Dapr in no time. You'll understand how Dapr simplifies development while allowing you to work with multiple languages and platforms. Following a C# sample, you'll understand how Dapr's runtime, building blocks, and software development kits (SDKs) help you to simplify the creation of resilient and portable microservices. Dapr provides an event-driven runtime that supports the essential features you need for building microservices, including service invocation, state management, and publish/subscribe messaging. You'll explore all of those in addition to various other advanced features with this practical guide to learning Dapr. With a focus on deploying the Dapr sample application to an Azure Kubernetes Service cluster and to the Azure Container Apps serverless platform, you’ll see how to expose the Dapr application with NGINX, YARP, and Azure API Management. By the end of this book, you'll be able to write microservices easily by implementing industry best practices to solve problems related to distributed systems.

Comparing HTTP and gRPC for Dapr

gRPC is a high-performance, open source, universal RPC framework that became extremely popular in the inter-microservices communication space because of its efficiency. gRPC leverages HTTP/2 for transport and adopts the binary serialization format Protobuf.

gRPC in .NET

There are several documents and blog posts on how to implement gRPC servers in Dapr, including articles from the .NET documentation on gRPC, https://docs.microsoft.com/en-us/aspnet/core/tutorials/grpc/grpc-start?tabs=visual-studio-code, and the (not specific to .NET) Dapr documentation on the gRPC service, https://docs.dapr.io/operations/configuration/grpc/.

gRPC is a Cloud Native Computing Foundation (CNCF) incubating project.

Let’s explore how we can leverage gRPC in ASP.NET and then how to apply it to Dapr.

gRPC in ASP.NET

In ASP.NET, we are so used to the combination of HTTP and JSON that we tend to think of these two as the only transport and format choices...
