AZ-220 Study Guide: Microsoft Azure IoT Developer

If you are a Developer focusing on Internet of Things (IoT) solutions on Microsoft Azure, then the AZ-220 Microsoft Azure IoT Developer is for you. I am currently preparing for that exam, so I want to share my AZ-220 Microsoft Azure IoT Developer Certification Exam Study Guide with you. If you are passing the AZ-220 exam, you will earn the Microsoft Certified: Azure IoT Developer Specialty certification, that you understand how to implement the Azure services that form an IoT solution, including data analysis, data processing, data storage options, and platform-as-a-service options. IoT Developers must be able to recognize Azure IoT service configuration settings within the code portion of an IoT solution.

To learn and prepare for the exam, I usually use a couple of online resources, mainly Microsoft Docs and Microsoft Learn, which I am going to share with you. You can find more information about how I prepare for a Microsoft Certification exam on my blog post: How to prepare and pass Microsoft Certification Exam.
