Hands-On Microservices with C# 8 and .NET Core 3 - Third Edition

By: Gaurav Aroraa, Ed Price

Overview of this book

<p>The microservice architectural style promotes the development of complex applications as a suite of small services based on specific business capabilities. With this book, you'll take a hands-on approach to build microservices and deploy them using ASP .NET Core and Microsoft Azure. </p><p>You'll start by understanding the concept of microservices and their fundamental characteristics. This microservices book will then introduce a real-world app built as a monolith, currently struggling under increased demand and complexity, and guide you in its transition to microservices using the latest features of C# 8 and .NET Core 3. You'll identify service boundaries, split the application into multiple microservices, and define service contracts. You'll also explore how to configure, deploy, and monitor microservices using Docker and Kubernetes, and implement autoscaling in a microservices architecture for enhanced productivity. Once you've got to grips with reactive microservices, you'll discover how keeping your code base simple enables you to focus on what's important rather than on messy asynchronous calls. Finally, you'll delve into various design patterns and best practices for creating enterprise-ready microservice applications. </p><p>By the end of this book, you'll be able to deconstruct a monolith successfully to create well-defined microservices.</p>

DDD and its importance for microservices

Domain-Driven Design (DDD) is a method and a process for designing complex systems. In this section, we will briefly discuss DDD and how it is important in the context of microservices.

Domain model design

The main objective of domain design is to understand the exact domain problems and then draft a model that can be written in any language or set of technologies. For example, in our FlixOne bookstore application, we need to understand order management and stock management.

Here are a few characteristics of the domain-driven model:

  • A domain model should focus on a specific business model and not multiple business models.
  • It should be reusable.
  • It should...
