Practical Microservices with Dapr and .NET

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

In this chapter, we explored the I/O binding building blocks of Dapr, and we learned how, with Twilio output binding, we can notify customers via text message without having to deal with libraries, SDKs, and the plumbing code, as it all boils down to a simple call to the Dapr runtime.

We then established a communication channel between a microservice of our sample e-commerce architecture with an external subsystem; both are unaware of each other’s implementation details, and our microservice is unaware of how to interact with Azure Event Hubs as the messaging bus.

The reservation-service application is placed at the center of our sample architecture, unlike the other microservices.

As a point of attention, the sample code doesn’t deal with application-level retries, which could be relevant if the strong consistency of state management and an elevated request rate prevent a reservation from always completing nicely. While this condition should be addressed...
