Introduction

Here at Avnet, we've created lots of different hands-on labs, blogs and videos to help new Azure Sphere developers come up to speed quickly.  This blog lays out a training plan leveraging these materials.  

How to use this training plan

I recommend completing each step of the plan in order.  The security features of Azure Sphere are discussed in the video presentations; you'll notice that we don't need to implement any security features when we develop Azure Sphere applications. 

There are 3 different "connected" labs.  Each connected lab leverages the same Azure Sphere example project, but connects it to either a generic IoTHub, IoTCentral application, or Avnet's IoTConnect cloud platform.  Each of these cloud solutions use one or more Azure IoT Hubs for the Azure Sphere device connection to the cloud.  You should select the connected lab that aligns with your target Cloud Solution.  

Azure Sphere Training Plan

on 1/20/2022 we kicked off a 3-part webinar series diving deep into Azure Sphere development.  This blog will be updated as the webinar series progresses and as new materials are created.
