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.

Building an e-commerce architecture

The objective of this book is to illustrate how Dapr can support your job, as developers and architects, in creating an application that adopts a microservice architecture. I think it has helped to discuss a hypothetical scenario over the course of this book to see how each feature can be introduced. I considered a scenario we will all experience once or more in our daily lives, mostly as consumers (sometimes as creators), when building an e-commerce site.

An e-commerce site must support many capabilities: exposing a catalog and making it browsable, having a price model that can be influenced by a promotion engine, managing a shopping cart, collecting customer information, processing orders, fulfilling the orders, and coordinating the shipments, just to name a few.

Throughout this book, we will compose a sample solution for the fictional e-commerce site named Biscotti Brutti Ma Buoni. This site specializes in baking and customizing cookies...
