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.

Summary

So far in this book, we learned how to use the Dapr building blocks to develop microservices. Starting with Chapter 4 up to Chapter 8, we managed to package and deploy our Dapr application to an AKS Kubernetes cluster in Azure in Chapter 9.

In this chapter, we learned two different approaches to selectively expose these Dapr applications to clients located externally of the cluster.

First, we experimented with NGINX to understand how to infuse Dapr into an existing application, without any change but instead working on the configuration the reverse proxy relies upon to define ingress rules. In addition to being a valid way to expose the Dapr application, this offers a perspective on how to introduce Dapr into an application without an SDK or any other modification.

Secondly, we explored how APIM can help us define and manage an API exposed to external clients and applications. There is much more to learn about APIM; in this chapter, we focused on the native integration...
