Hands-On Edge Analytics with Azure IoT

By: Colin Dow

Overview of this book

Edge analytics has gained attention as the IoT model for connected devices rises in popularity. This guide will give you insights into edge analytics as a data analysis model, and help you understand why it’s gaining momentum. You'll begin with the key concepts and components used in an edge analytics app. Moving ahead, you'll delve into communication protocols to understand how sensors send their data to computers or microcontrollers. Next, the book will demonstrate how to design modern edge analytics apps that take advantage of the processing power of modern single-board computers and microcontrollers. Later, you'll explore Microsoft Azure IoT Edge, MicroPython, and the OpenCV visual recognition library. As you progress, you'll cover techniques for processing AI functionalities from the server side to the sensory side of IoT. You'll even get hands-on with designing a smart doorbell system using the technologies you’ve learned. To remove vulnerabilities in the overall edge analytics architecture, you'll discover ways to overcome security and privacy challenges. Finally, you'll use tools to audit and perform real-time monitoring of incoming data and generate alerts for the infrastructure. By the end of this book, you'll have learned how to use edge analytics programming techniques and be able to implement automated analytical computations.

Working with Microsoft Azure IoT Hub

In Chapter 1, Introduction to Edge Analytics, we touched on Azure IoT Edge and Azure IoT. In this chapter, we will start to work with Azure IoT services using Microsoft Azure. The lessons learned from this will provide a good background for Chapter 5, Using the Raspberry Pi with Azure IoT Edge.

We will create a Microsoft Azure account and then proceed to log in to the Azure portal. We will take a brief look at the portal and move on to creating an IoT hub resource. We will transmit simulated data to the IoT hub from a Python client and view it using a Microsoft utility called Device Explorer.

In this chapter, we will cover the following topics:

  • What is Microsoft Azure?
  • What is Azure IoT Hub?
  • A quick tutorial on Azure IoT Hub
