Building Microservices with .NET Core 2.0 - Second Edition

By: Gaurav Aroraa

Overview of this book

The microservices architectural style promotes the development of complex applications as a suite of small services based on business capabilities. This book will help you identify the appropriate service boundaries within your business. We'll start by looking at what microservices are and their main characteristics. Moving forward, you will be introduced to real-life application scenarios; after assessing the current issues, we will begin the journey of transforming this application by splitting it into a suite of microservices using C# 7.0 with .NET Core 2.0. You will identify service boundaries, split the application into multiple microservices, and define service contracts. You will find out how to configure, deploy, and monitor microservices, and configure scaling to allow the application to quickly adapt to increased demand in the future. With an introduction to reactive microservices, you’ll strategically gain further value to keep your code base simple, focusing on what is more important rather than on messy asynchronous calls.

Monolith transitioning

As part of our exercise, we decided to transition our existing monolithic application FlixOne to a microservice-styled 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 it provides in regard to cost, security, and scalability, apart from technology independence. This also aligns the application more with the business goals.

The entire process of transitioning requires you to identify seams that act like 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 talked about how module interdependency, team structure, database, and technology are a few probable candidates. Special care is required...
