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>

Managing Azure API Management as an API gateway

Another important pattern in a microservice's implementation is backends for frontends (BFF). This pattern was introduced and made popular by Sam Newman. The actual implementation of the BFF pattern is done by introducing an API gateway between various types of clients and microservices.

This is depicted in the following diagram:

Azure API Management (henceforth referred to as Azure APIM or just APIM ) is just the right fit. It can act as an API gateway in .NET-based microservice implementations. Since Azure APIM is one of the cloud services, it is ultra-scalable and can be integrated well within the Azure ecosystem. In this chapter, we will focus on showing you the features of Azure APIM.

Azure APIM is logically divided into three parts:

  • API gateway: The API gateway is basically a proxy between client...
