Distributed .NET with Microsoft Orleans

By: Bhupesh Guptha Muthiyalu, Suneel Kumar Kunani

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.

Chapter 5: Persistence in Grains

In the last chapter, we learned about Orleans grains and silos, which host grains. We also learned about one of the most prominent hosting patterns, co-hosting Orleans applications with an ASP.NET Core application. The grains we built in the last chapter do not have any state associated with them. In the real world, most applications will deal with data. This data (or state as we call it) should be stored in some persistent storage and be presented to the client application when needed.

In this chapter, we will learn how we manage state in Orleans, and in due course, we will cover the following topics:

  • Understanding grain state persistence
  • Creating a custom state provider
  • Grains with multiple states
  • Grains directly interacting with a database
