Hello cloud marathoners,
Two weeks ago, I was able to clear the Azure specialty exam – “Azure IoT Developer” and get certified. More importantly, this was a good opportunity to learn about IoT technologies and services in Azure platform.
What is IoT?
An “Internet of Things” (IoT) device is typically made up of a circuit board with sensors attached that use WiFi to connect to the internet. Here are some examples of IoT devices and use cases:
- A pressure sensor on a remote oil pump.
- Temperature and humidity sensors in an air-conditioning unit.
- An accelerometer in an elevator.
- Presence sensors in a room.
The Azure Internet of Things (IoT) is a collection of Microsoft-managed cloud services that connect, monitor, and control billions of IoT assets. In simpler terms, an IoT solution is made up of one or more IoT devices that communicate with one or more back-end services hosted in the cloud.
Check out the following short video, if you never hear about applications of Internet of Things (aka, IoT).
Is there a comprehesive study guide to follow?
The short answer is YES!
As always start with simple and straight forward Microsoft Learn modules on IoT learning path. But that is not the only resource that i have used.
I personally found it very useful to check the Microsoft Tech community blog posts. The IoT sub-section has many tricks and trips and recommendations. Thus, check the following post that has very good information on exam resources:
AZ-220 IoT Developer Certification Study Guide – is an awesome post from Microsoft employee Paul DeCarlo. By following this post I got many answers on the following questions:
- How do I know which topics to focus on, what skills does the AZ-220 exam measure?
- Where can I learn how to apply the concepts measured on the AZ-220 exam in a practical / hands-on manner?
- I prefer to learn at my leisure with video content, are there any resources that cover the materials in the official docs and Microsoft Learn that I can watch?
- Any thoughts on paid courses / practice exams, are there any recommendations?
Where can I get Azure IoT Samples in C# ?
I have used the following GitHub repo in order to get hands-on expereince with Azure IoT. Azure IoT Samples for C# (.NET)
What is next?
Check this awesome IoT Event Learning Path.
It is designed for Solution Architects, Business Decision Makers, and Development teams that are interested in building IoT Solutions with Azure Services. The content is comprised of 5 video based modules that approach topics ranging from IoT device connectivity, IoT data communication strategies, use of artificial intelligence at the edge, data processing considerations for IoT data, and IoT solutioning based on the Azure IoT reference architecture.
Thank you for reading this post till this point.
Please, feel free to share your experience, as i am planning to keep this post up to date with your valuable contributions going forward. #keeplearning
