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 6: Scheduling and Notifying in Orleans

It is a very common requirement in any application or product to execute a task/job at a specified date-time or a specified interval on a recurring schedule. A very common example of scheduling in our day-to-day life is alarms and reminders that we get from devices and apps such as phones, Outlook, and so on. The Orleans runtime provides us with two features, called timers and reminders, that enable the developer to achieve scheduling in grains.

It is also a very common requirement to send asynchronous notifications to clients. The Orleans runtime provides a feature called observers through which we can send notifications in grains.

This chapter will cover the following:

  • Understanding and implementing timers
  • Understanding and implementing reminders
  • Understanding and implementing notifications
