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.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The –-debug * option of the Tye command waits for VS Code debug sessions to be attached to each service.”

A block of code is set as follows:

"compounds":
   [
     {
       "name": "webApi + webApi2 w/Dapr",
       "configurations": [".NET Core Launch w/Dapr
         (webapi)", ".NET Core Launch w/Dapr (webapi2)"]
     }
   ]

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

     {
        "name": ".NET Core Launch w/Dapr (webapi2)",
        "type": "coreclr",
        "request": "launch",
        "preLaunchTask": "daprd-debug-webapi2",

Any command-line input or output is written as follows:

PS C:\> curl http://localhost:60151/v1.0/invoke/hello-world/method/hello
Hello, World

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Once we activate debugging in VS Code by selecting the .NET Core Launch (web) with Dapr configuration, this is what happens.”
