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.

Setting up Kubernetes

While the discussion around microservice architectures has evolved independently, the concept of containerized deployments has propelled its popularity among developers and architects.

Once you start to have a multitude of microservices, each comprised of one or many containers, you soon realize you need a piece of software that can orchestrate these containers. In a nutshell, orchestration is the reason why Kubernetes is so relevant and frequently appears in the context of microservice architectures.

Important note

Kubernetes (k8s) is the most popular open source container orchestrator and is a project that’s maintained by the Cloud Native Computing Foundation (CNCF). To learn more about Kubernetes, I suggest that you read straight from the source at https://kubernetes.io/docs/concepts/overview/what-is-kubernetes/.

In this section, we are going to provision an Azure Kubernetes Service (AKS) cluster. Even if it is not in this book’s scope...
