Practical Microservices with Dapr and .NET

By: Davide Bedin

Overview of this book

Over the last decade, there has been a huge shift from heavily coded monolithic applications to finer, self-contained microservices. Dapr is a new, open source project by Microsoft that provides proven techniques and best practices for developing modern applications. It offers platform-agnostic features for running your applications on public cloud, on-premises, and even on edge devices. This book 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 offers ease of implementation while allowing you to work with multiple languages and platforms. You'll also understand how Dapr's runtime, services, 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 to build 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. By the end of this book, you'll be able to write microservices easily using your choice of language or framework by implementing industry best practices to solve problems related to distributed systems.

HTTP and gRPC for Dapr services

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.

Note

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 incubated project.

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 for a web API.

With the growth in popularity of gRPC and the ability to use it from ASP.NET too, we can...
