Azure IoT: Turn Device Data into Insights and Action

Most IoT tutorials stop at the device. They show you how to connect hardware, send some data to the cloud, and call it done. And that's often where it ends.

In this course, that's just the beginning.

By the end, you'll have built a complete, working IoT data pipeline in Azure, from a connected device all the way to real-time dashboards and automated alerts. And no, you won't need any hardware. Or much code, for that matter.

The architecture you'll build is based on a real pattern used in production IoT solutions: the cold, warm, and hot path. Each path handles data differently depending on how urgent it is. A sensor value that might indicate a machine is overheating? That needs to be acted on immediately. Historical data for trend analysis? That can wait. By the end of the course, you'll understand the difference and know how to build both.

How the course works

Throughout the course we follow one concrete scenario: a device that sends temperature and humidity readings to the cloud. Simple enough to follow, but realistic enough to be useful.

We start by getting that device connected and sending its first messages, and this might surprise you: that part is easier than most people expect. From there, we gradually build out the full architecture. Each module adds another layer to the solution, so by the end you have a complete picture rather than a collection of isolated demos.

The course is demo-heavy by design. Theory is kept to the minimum needed to understand what you're building and why. No heavy coding either. Any scripts or queries used in the demos are available in the GitHub repository that comes with the course.

Who this course is for

This course is a good fit if you're a developer or cloud professional who wants to understand how IoT data processing actually works in Azure, and build it yourself. You don't need prior IoT or cloud experience to get started.

If you're working with data or AI in Azure and want to understand where that data comes from and how IoT pipelines feed into those systems, this course gives you that foundation.

It's not the right fit if you're looking for embedded systems or hardware setup. This course focuses on the cloud side of things.

What's covered

Eight modules, more than four hours of video content:

1. Course introduction

2. Introduction to Azure IoT — the cloud, IoT concepts, and the cold/warm/hot architecture

3. Getting started hands-on — create an IoT Hub, connect a device, send your first messages

4. IoT Hub messaging — message format, protocols, cloud-to-device messages, and message routing

5. Cold path — long-term storage with Azure Storage

6. Warm path — querying and visualizing data with Azure Data Explorer and KQL

7. Hot path — real-time detection and automated alerts with Stream Analytics, Event Hub, and Logic Apps

8. Final solution recap — the complete architecture end-to-end

All scripts, queries, and CLI commands used in the demos are available in the GitHub repository that comes with the course.
