How does Azure integrate with IoT devices for real-time data processing?

Question

I’m interested in understanding how Azure integrates with IoT devices to enable real-time data processing. What services and tools does Azure offer to process, store, and analyze IoT data streams efficiently? Any examples of how businesses are using Azure to power IoT applications?

Hello @Mofazzel Hosen Morshed,

welcome to this moderated Azure community forum.

Microsoft provides a wide range of IoT related services and PaaS services that can combined into a full IoT solution.

This reference architecture is a good starting point.

Check this documentation about more industry specific reference archtectures.

Some resources used are:

• IoT Hub: a cloud gateway for registering devices at scale so each device supports device-to-cloud and cloud-to-device communication with an secured individual identity. I can also route messages to other Azure resources based on rules
• Device Provisioning Service: a solution to act as front office to point devices to specific IoT Hub based on certain rules
• Azure Event Grid MQTT Broker support: a cloud gateway to connect devices at scale when just the plain MQTT protocol is needed or supported
• Azure Stream Analytics: services capable of routing messages from input streams to output streams based on a SQL like language. This is a very powerful language capable of offering joining of message streams, aggregations etc. based on time windows, geospatial support, etc.
• Azure Data Explorer. A very, very powerful timeseries database specialized in ingesting and querying time related facts (like IoT telemetry) for real-time dashboarding
• Managed Grafana: Grafana dashboards with full AAD (Entra ID) integration
• Azure IoT Edge: the edge solution for running compute logic on the edge of the local network that can be fully controlled at scale in the cloud (the IoT Hub) and even offers offline support so the edge keeps ingesting data even when the cloud is temporarily not available.
• Azure IoT Operations. The new edge solution based on Kubernetes so it offers high availability and fail over (notice that more powerful hardware is needed as edge nodes)

There are many solution built in Azure IoT. Check out this and this and this example, both based on Azure IoT Edge together with a cloud solution.

If you are interested in how real-time insights can be offered with Azure check out this series of blog posts.

Microsoft MS Learn provides several learning modules and paths regarding Azure IoT. Check this collection with several other modules too.
