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>

Revisiting the application

This section will explore what we are going to develop. Throughout this book, we've used various APIs, to showcase the code examples within. In this section, we will get an overview of our sample application, which is a combination of various flows, where the end user enters the application and he/she processes the request to buy books.

The following diagram provides an overview of our application:

The preceding diagram is a pictorial representation of the functional overview of our sample application, and it shows the flow, which contains the following items:

  • Client apps: Mobile and web applications are the client apps that the end user is going to use. Our code repository is shipped with the web application.
  • Auth server: It validates the user and generates the JWT token, for further processing.
  • RESTful services: These are the various services...
