Azure IoT explained

A group of Microsoft-managed cloud services known as the Azure Internet of Things (IoT). Azure IoT hub connects, keeps track of, and manages billions of IoT assets. To put it simply, an IoT solution consists of one or more IoT devices that connect to one or more back-end services stored in the cloud.

IoT devices

A typical IoT device consists of a circuit board with sensors connected, which connects to the internet through WiFi. For instance:

  • A remote oil pump’s pressure sensor.
  • Sensors for temperature and humidity in an air conditioner.
  • An elevator’s accelerometer
  • presence detectors in the space.

For building your solution, a large range of devices from various vendors are available. Visit Akenza for a list of gadgets approved to function with Azure IoT Hub. You can utilize tools like a Raspberry Pi or an MXChip IoT DevKit for prototyping.


Azure IoT hub provides IoT devices that often transmit telemetry from the sensors to cloud-based back-end services. Other forms of communication, such as a back-end service relaying orders to your gadgets, are nevertheless conceivable. Examples of device-to-cloud and cloud-to-device communication include the following:

  • A mobile refrigeration vehicle provides temperature data to an Azure IoT hub every five minutes.
  • To assist in problem diagnosis, the back-end service instructs a device to alter the frequency at which it transmits telemetry.

A device can deliver alerts based on the data gathered by its sensors. For instance, when the temperature of a batch reactor in a chemical plant surpasses a given threshold, a piece of monitoring equipment transmits an alert.

Your gadgets transmit data for a dashboard display that operators can see. For instance, a refinery’s control room might display the temperature, pressure, and flow rates in each pipe, allowing operators to keep an eye on the plant.

Common communication protocols, including HTTP, MQTT, and AMQP, are supported by the IoT Device SDKs and IoT Hub. IoT devices differ from conventional clients like browsers and mobile apps in terms of their properties. The difficulty of safely and consistently tying devices to your back-end service is overcome with the device SDKs.

In particular, IoT devices:

  • Embedded systems frequently lack a human operator (unlike a phone).
  • It can be used in remote regions with expensive physical access.
  • Possibly only accessible from the rear end of the solution.
  • Has possibly finite processing and power capabilities.
  • It may have sporadic, expensive, or slow network connectivity.
  • Use of exclusive, unique, or sector-specific application protocols may be necessary.

Back-end services

The back-end service of an IoT solution offers features like selecting how to process and store that data after receiving telemetry at scale from your devices.

  • Telemetry analysis to provide insights, either immediately or afterward.
  • Sending instructions to a particular gadget from the cloud.
  • Managing which devices can connect to your infrastructure and provisioning devices.
  • Controlling the condition of your equipment and keeping an eye on its usage.
  • Taking control of the gadget firmware you have loaded.

For instance, the cloud back ends in a remote monitoring solution for an oil pumping station and analyses telemetry from the pumps to spot unusual behavior. A command to take corrective action can be automatically sent back to the device by the back-end service when it discovers an anomaly. The gadget and cloud create an automated feedback loop as a result of this procedure, considerably enhancing the effectiveness of the proposed solution.

Why is MQTT important for IoT?

MQTT has got its recognition as the leading protocol for IoT solutions in recent years. There are various reasons for this. Firstly, one of the IoT protocols that are now used is the lightest. Since it is an open standard, any hardware or software can use it. The availability of client libraries for all popular programming languages makes it simple to create IoT applications utilizing MQTT.

MQTT’s flexibility makes it feasible to handle various IoT project designs and use case types, thanks to the publish and subscribe paradigm. Notably, since the broker manages all connections, publishers and subscribers of the system don’t even need to be aware of one another’s existence. The protocol enables highly scalable projects to be implemented, potentially enabling the connection of millions of IoT devices in a single system. Broadcasting messages to numerous devices simultaneously is possible thanks to MQTT’s bi-directional connection. Finally, MQTT provides a wide range of data security measures, including TLS encryption.

Final Words

Use the IoT industry’s largest and fastest-growing partner network. Customers can select a fully managed or finished solution from the Azure IoT hub and access the knowledge and resources to estimate costs for new solutions. And Akenza is all you need if you want to access an IoT platform quickly.

The main goal of Akenza is to give many users simple access to the Azure IoT hub. Solutions that support an agile approach to development and innovation are required in today’s highly volatile technology landscape. We are confident that we can guide the Internet of Things into a widespread market application by significantly decreasing the time and complexity that businesses must expend when developing IoT solutions. There are countless scenarios in which we could connect our environment. It comes down to awareness, expense, and complexity.
