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>

Building a greenfield application

Previous chapters have discussed monolith applications (brownfield), and then we transitioned a monolith to a new microservice application (greenfield). In this section, we will create a FlixOne bookstore from scratch.

A brownfield application is already developed (like a monolith application), whereas a greenfield application is one created from scratch.

First, we will scope out our microservices and their functionalities, and we will identify inter-service interactions as well.

Our FlixOne bookstore will have the following set of functionalities available:

  • Searching through the available books
  • Filtering books on the basis of categories
  • Adding books to the shopping cart
  • Making changes to the shopping cart
  • Placing an order from the shopping cart
  • User authentication

Creating a greenfield application requires a lot of effort, to meet the business...
