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>

Exploring OpenID Connect

OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. OpenID Connect is all about authentication. It allows clients to verify end users, based on the authentication that was performed by an authorization server. It is also used to obtain basic profile information about the end user, in an interoperable and REST-like manner.

OpenID Connect allows clients of all types—web-based, mobile, and JavaScript—to request and receive information about authenticated sessions and end users. We know that OAuth 2.0 defines access tokens. Well, OpenID Connect defines a standardized identity token (commonly referred to as the ID token). The identity token is sent to the application, so that the application can validate who the user is. It defines an endpoint to get identity information for that user, such as their name or...
