Overview of this book

Building distributed applications in this modern era can be a tedious task as customers expect high availability, high performance, and improved resilience. With the help of this book, you'll discover how you can harness the power of Microsoft Orleans to build impressive distributed applications. Distributed .NET with Microsoft Orleans will demonstrate how to leverage Orleans to build highly scalable distributed applications step by step in the least possible time and with minimum effort. You'll explore some of the key concepts of Microsoft Orleans, including the Orleans programming model, runtime, virtual actors, hosting, and deployment. As you advance, you'll become well-versed with important Orleans assets such as grains, silos, timers, and persistence. Throughout the book, you'll create a distributed application by adding key components to the application as you progress through each chapter and explore them in detail. By the end of this book, you'll have developed the confidence and skills required to build distributed applications using Microsoft Orleans and deploy them in Microsoft Azure.

Leveraging Azure Kubernetes hosting

The Microsoft.Orleans.Hosting.Kubernetes NuGet package provides support for hosting a Microsoft Orleans application in Azure Kubernetes. ISiloBuilder.UseKubernetesHosting is the extension method provided by the NuGet package. You can add this NuGet Package to the Distel.WebHost project and update Program.cs to use siloBuilder.UseKubernetesHosting() instead of siloBuilder.UseLocalhostClustering(), as shown here:

<<Code removed for brevity>>
builder.Host.UseOrleans(siloBuilder =>
{
// In Kubernetes, we use environment variables and the pod
   manifest
siloBuilder.UseKubernetesHosting();       
});
<<Code removed for brevity>>

The siloBuilder.UseKubernetesHosting() method will take care of the following steps and hosting an Orleans application in a Kubernetes cluster:

  • Setting the SiloOptions.SiloName property with the pod name.
  • Setting the EndpointOptions...
