How to create an IoT Hub in Microsoft Azure – An Easy Guide

Introduction

Microsoft Azure is a powerful cloud platform that allows you to provision infrastructure, deploy applications and manage devices quickly. You can also use it for IoT projects by creating Azure’s internet of things hub.

IoT Hub

The IoT Hub is a broker that receives and sends data to other devices. It’s a main location where a person can connect your devices, manage them, and monitor their status. You can use it with Azure IoT Central or MQTT, two communication protocols that send messages between the device and the cloud platform.

What is MQTT?

MQTT is a basis to transfer and communicate messages within or between two devices enrolled in an Azure IoT hub. It initiates Bilateral or two-way communication between the Publisher (sender) and the subscriber (receiver).

Creating a new hub

  • To create a new Azure IoT Hub, go to the Azure portal and then click on “Create.” This will leave you to the Hubs page, from where you can select between creating a new one or using your existing one. It would help if you chose “Use an existing subscription” to use your current subscription for this project.
  • To use your existing subscription, you must first log into it with your Microsoft account credentials (for example johndoe@microsoft).
  • Once logged in, select “Add More” from the top menu bar and choose “New Subscription.”
  • A window will appear asking if this will be used for something else too (like building out features), so answer yes if so!
  • Now you need someone else’s email address who has access rights over their own computer/device(s) because otherwise, they won’t get notified when something happens, such as changes happening within Azure itself; otherwise known as notifications/alerts being sent out automatically via email when certain events occur throughout each day which may include software updates happening regularly without fail at all times regardless whether anyone ever notices these things happening instantly right away upon logging back into their computer after being away from home during vacation time off work hours spent away from regular office duties altogether.

Connecting a device to the hub

  • Device registration: This step is required for all devices connected to the Azure IoT Hub. You must register each networked device with its unique identifier so that it can be accessed remotely by other users on the internet of things hub without having access credentials stored locally on each device. You will be asked for a name and password for your device, which will be held in Azure Active Directory (Azure AD). If you have not prepared an Azure AD account, click Sign In at the top right corner of your screen and select Microsoft Account or another sign-in method.
  • Device authentication: After registering devices with their respective identifiers, they need authentication before they can start communicating over Wi-Fi networks or connecting via cellular data connections like LTE or 3G/4G cellular networks.
  • Device connection: Once authenticated successfully using their respective identifiers and passwords associated with those accounts created during the registration process above.

IoT Central

IoT Central is a simple way to get started with Azure. It’s available for Mac, Windows, and Linux, and it’s a browser-based application that runs on your local machine or in the cloud.

It offers you everything that you will need to create a connected device (like a bright light bulb) that can be managed remotely through the internet. This means that you’ll be able to turn lights on/off from anywhere in the world at any time–and if someone else wants access too. No problem! We’ll give them access so they can also use their own devices.

 

A hub is a simple way to get started with Azure.

A hub is a simple way to get started with Azure. It’s a fully managed service that lets you build and deploy IoT solutions, including cloud-based devices, sensors, and software.

The hub provides the essential components necessary for an IoT solution: connectivity between devices on the network and analytics reports about those connections.

A hub can be used for many things—from automating home security systems to tracking vehicle miles traveled by drivers at work or in their cars—and it’s scalable so you can add more devices or scale down as needed.

Conclusion

As here you can see, there are several ways to connect devices to Azure IoT Hub. This article covered the basics of creating an Azure IoT hub. We also showed you how to connect your device via MQTT and make sure it knows where the data is coming from. We also covered the basics and importance of Azure IoT Hub and how MQTT plays a vital role.
