The Azure IoT Handbook

By: Dan Clark

Overview of this book

With the rise of cloud-based computing, deploying IoT systems has become more cost-effective for businesses. This transformation has led to developers and architects shouldering the responsibility of creating, managing, and securing these systems, even if they are new to the IoT technology. The Azure IoT Handbook is a comprehensive introduction to quickly bring you up to speed in this rapidly evolving landscape. Starting with the basic building blocks of any IoT system, this book guides you through mobile device management and data collection using an IoT hub. You’ll explore essential tools for system security and monitoring. Following data collection, you’ll delve into real-time data analytics using Azure Stream Analytics and view real-time streaming on a Power BI dashboard. Packed with real-world examples, this book covers common IoT use as well. By the end of this IoT book, you’ll know how to design and develop IoT solutions leveraging intelligent edge-to-cloud technologies implemented on Azure.

Exploring message enrichment

Message enrichment in an IoT hub refers to the process of enhancing or augmenting incoming messages from IoT devices with additional information or metadata before they are routed or processed further. This enrichment can include adding contextual data, transforming the message format, or enriching the message payload with additional attributes.

IoT Hub provides a feature called message enrichments that allows you to configure rules to enrich messages as they pass through the hub. These rules can be defined based on specific criteria or conditions, and they enable you to modify messages by adding, updating, or deleting message properties or inserting custom data.

Here are a few common scenarios where message enrichment can be useful:

  • Adding metadata: You can enrich messages with additional metadata such as device properties, location information, or timestamp information. This metadata can provide context to the message and help in downstream...
