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.

Learning about the Azure Container Apps architecture

Azure Container Apps is a managed serverless container service on the Microsoft Azure cloud.

It is managed in the sense that you, the user, can configure the service to fit your needs but you are not involved in the management of the underlying resources; it is serverless as you do not have to care about the characteristics and scaling of the VMs used by the underlying hosting platform.

With Azure Container Apps, your application does run on an Azure Kubernetes Service (AKS) cluster managed on your behalf by the Azure platform: you will not have to configure and maintain the resource by yourself.

Here are the three main components of Azure Container Apps:

  • KEDA is already configured, ready to be used to scale your workload based on HTTP requests, CPU, and memory usage, or any of the other scale triggers supported by KEDA
  • Dapr is integrated into Azure Container Apps, so it can be leveraged by any container...
