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>

Refactoring the Monolith

In the previous chapter, we discussed the problems of a layered monolith architecture. This chapter aims to discuss the transitioning of monolithic- to microservices-based applications. We will start this chapter with a discussion of our new tech stack (C# and Entity Framework), then move on to the features of a good service and how we can refactor them from an existing system and build separate microservices for products and orders.

We will cover the following topics:

  • Understanding the current and new technology stack
  • The size of microservices
  • What makes a good service?
  • Understanding the concept of seam
  • Communication between microservices
  • Revisiting the FlixOne case study
