Hands-On Azure Digital Twins

By: Alexander Meijers

Overview of this book

In today’s world, clients are using more and more IoT sensors to monitor their business processes and assets. Think about collecting information such as pressure in an engine, the temperature, or a light switch being turned on or off in a room. The data collected can be used to create smart solutions for predicting future trends, creating simulations, and drawing insights using visualizations. This makes it beneficial for organizations to make digital twins, which are digital replicas of the real environment, to support these smart solutions. This book will help you understand the concept of digital twins and how it can be implemented using an Azure service called Azure Digital Twins. Starting with the requirements and installation of the Azure Digital Twins service, the book will explain the definition language used for modeling digital twins. From there, you'll go through each step of building digital twins using Azure Digital Twins and learn about the different SDKs and APIs and how to use them with several Azure services. Finally, you'll learn how digital twins can be used in practice with the help of several real-world scenarios. By the end of this book, you'll be confident in building and designing digital twins and integrating them with various Azure services.

Event notifications

Event notifications are an important part of event routing with Azure Digital Twins. Azure digital twins produce notifications based on different events. These events are routed to different locations within the same Azure digital twin or outside the Azure digital twin to an endpoint. Event notifications describe the notifications for these events. The following events will generate notifications:

Each notification is built up from a body and a header. The header contains several key-value pairs that differ based on the protocol being used. Notifications from Azure Digital Twins conform to the CloudEvents standard.

Understanding the CloudEvents Standard

The CloudEvents standard is a specification for describing event metadata in a standardized way. Their purpose is to simplify the standard model across services and platforms to provide seamless integration between the services of different platforms. CloudEvents is part of the CNCP...
