Practical Microservices with Dapr and .NET

By: Davide Bedin

Overview of this book

Over the last decade, there has been a huge shift from heavily coded monolithic applications to finer, self-contained microservices. Dapr is a new, open source project by Microsoft that provides proven techniques and best practices for developing modern applications. It offers platform-agnostic features for running your applications on public cloud, on-premises, and even on edge devices. This book 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 offers ease of implementation while allowing you to work with multiple languages and platforms. You'll also understand how Dapr's runtime, services, 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 to build 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. By the end of this book, you'll be able to write microservices easily using your choice of language or framework by implementing industry best practices to solve problems related to distributed systems.

Summary

In this chapter, we learned that the actor model that's supported by Dapr is a very powerful tool in our toolbox.

We understood the scenarios that benefit the most from applying actors, and how to avoid the most common implementation pitfalls.

By configuring Dapr Actors, from the state store to the ASP.NET perspective, we appreciated how the simplicity of Dapr extends to this building block too.

Next, we introduced an actor type to our existing architecture. By doing so, we learned how to separate the contract (interface) from the implementation and invoke it from other Dapr services.

Note that this is another example of how Dapr facilitates the development of microservice architectures by addressing the communication and discovery of services (how easy is it for a client to interact with an actor?). It also unleashes the independent evolution of our architecture's components; introducing actors in our example has been seamless for the rest of the services...
