Practical Microservices with Dapr and .NET

Use the new, enticing, and highly portable event-driven runtime to simplify building resilient and scalable microservices for cloud and edge applications

Key Features

• Build resilient, stateless, and stateful microservice applications that run on the cloud and edge
• Learn how to expose and operate Dapr applications with multiple options
• Solve common distributed systems such as low latency and scaling using any language and framework

Book Description

Dapr offers platform-agnostic features for running your applications anywhere, from the public cloud to edge deployments.

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 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. With a focus on deploying the Dapr sample application to an Azure Kubernetes Service cluster and to the Azure Container Apps serverless platform, the book will also teach you how to expose the Dapr application with NGINX, YARP, and Azure API Management.

By the end of this book, you'll write microservices easily by implementing industry best practices to solve problems related to distributed systems.

What you will learn

• Use Dapr to create services, invoking them directly and via pub/sub
• Discover best practices for working with microservice architectures
• Leverage the actor model to orchestrate data and behavior
• Expose API built with Dapr applications via NGINX and Azure API Management
• Use Azure Kubernetes Service to deploy a sample application
• Monitor Dapr applications using Zipkin, Prometheus, and Grafana
• Combine Dapr with a serverless platform learning Azure Container Apps
• Scale and load test Dapr applications on Kubernetes

Who This Book Is For

This book is for developers looking to explore microservices architectures and implement them in Dapr applications using Microsoft .NET examples. Whether you are new to microservices or have knowledge of this architectural approach and want to get hands-on experience in using Dapr, you’ll find this book useful. Familiarity with .NET will help you to understand the C# samples and code snippets used in the book.
