Practical Microservices with Dapr and .NET - Second Edition

By: Davide Bedin

Overview of this book

This second edition will help you get to grips with microservice architectures and how to manage application complexities with Dapr in no time. You'll understand how Dapr simplifies development while allowing you to work with multiple languages and platforms. Following a C# sample, you'll understand how Dapr's runtime, building blocks, and software development kits (SDKs) help you to simplify the creation of resilient and portable microservices. Dapr provides an event-driven runtime that supports the essential features you need for building microservices, including service invocation, state management, and publish/subscribe messaging. You'll explore all of those in addition to various other advanced features with this practical guide to learning Dapr. With a focus on deploying the Dapr sample application to an Azure Kubernetes Service cluster and to the Azure Container Apps serverless platform, you’ll see how to expose the Dapr application with NGINX, YARP, and Azure API Management. By the end of this book, you'll be able to write microservices easily by implementing industry best practices to solve problems related to distributed systems.

Daprizing ingress controllers

Let’s recap the current stage of our deployment of the Biscotti Brutti Ma Buoni backend solution to Kubernetes: after we followed all the steps in Chapter 9, Deployment to Kubernetes, we have the Dapr components and applications properly configured, and external calls can reach the APIs of some of our services.

Considering the approach that we followed in exposing the Dapr applications so far, how different has it been from exposing any other generic ASP.NET APIs? Not different at all: taking Dapr out of the picture, we still had to deal with Kubernetes-specific concepts such as services and then set these services as the backend of ingress rules using the NGINX Ingress Controller (IC) we set up.

As you might already guess from the direction the chapter is aiming toward, there are other approaches to inject Dapr into any existing application leveraging HTTP routes and, as an extension of this, an NGINX IC. We are now going to Daprize the NGINX...
