IoT Prototyping in Azure with Particle & Grove

Introduction

Today’s post will be on how I see the smoothest way to do prototyping & hobby projects in regards to IoT. What is my main principle in deciding this? I only want to spend time on “business logic” and not waste time on the nuts & bolts of the engine.

Architecture

So what’s the architecture we’ll be using for this?

1. Device : Particle Photon + Grove Expansion Board + Grove Sensors (Temperature & Air Quality )
2. Particle Platform : Used for the development
3. Azure IoT Hub : Basically a 1:1 link with Particle, which will take over once we go to a production grade setup.
4. Azure Stream Analytics : Streaming the ingest data from our IoT Hub towards our various landing zones.
5. Azure CosmosDB : For storing the data we’ll use in our reports.
6. Azure Storage Account : Cheap storage where we keep all the data we collected, and which we could use for our analytics.
7. PowerBI : The make nice reports of the data we collected. 😉

Now let’s delve into these parts one by one!

Taking a look under the hood of the Linux VM Authentication

Introduction

Today we’ll do a deep-dive into how you can log into an Azure Linux VM with Azure Active Directory (AAD). In essence, we’ll go through the following documentation flow, and then take a look how that looks under the hood.

 

Part one : “Creation”

The part on creating & integrating the VM is VERY straightforward…

• Create a resource group
  
• Create a Linux virtual machine
  
• Add the “Azure AD login VM”-extension
  

And that’s it! Really, that’s it…
