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>

Understanding how monolith transitioning works

As part of our exercise, we decided to transition our existing monolithic application, FlixOne, to a microservice-style architecture. We saw how to identify decomposition candidates within a monolith, based on the following parameters:

  • Code complexity
  • Technology adoption
  • Resource requirement
  • Human dependency

There are definite advantages that it provides, with regard to cost, security, and scalability, apart from technology independence. This also aligns the application more with our business goals.

The entire process of transitioning requires you to identify seams that act like the boundaries of your microservices, along which you can start the separation. You have to be careful about picking up seams on the right parameters. We have discussed how module interdependency, team structure, database, and technology are a few probable...
