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 common IoT events

In an IoT environment, a wide range of events can be sent to an event grid to enable real-time communication, data processing, and automation. Here are some common IoT events that are typically sent to an event grid:

  • Sensor data updates: This is one of the most common types of IoT events. It includes data from various sensors such as temperature, humidity, light, motion, and more. These updates can trigger actions such as alerts, data storage, or analytics.
  • Device status changes: Events indicating changes in the status of IoT devices, such as device startup, shutdown, reboot, or connectivity status changes. These events can help in monitoring and managing the health of IoT devices.
  • Alarm and alert events: IoT devices often generate events when certain thresholds or conditions are met. For example, a smoke detector might send an event when it detects smoke, or a security camera might trigger an event when it detects motion.
  • Device firmware...
