Is IoT Hub necessary?

Good afternoon,

I am learning about different services on Azure as I want to connect our TTN applications to the cloud. The goal is to receive the data from the sensors, store and visualize it at any time.

I have read tons of articles on the topic, but still cannot completely understand the IoT Hub service.

For our particular case with about 10-15 sensors do I really need the IoT Hub service or can simply use Functions service (for HTTP requests from the ttn server) and influxdb (from the marketplace) to store the data and visualize it. Would it be a reasonable backend architecture?

Thanks in advance.

Hello @TetianaLavrenko-3216 ,
Thanks for the great question :). I don't want to guide you in the wrong direction therefore can you confirm:

  1. That by TTN you mean The Things Network?

  2. Is the data already in the cloud and you don't want to customize (or you can't customize even if you wanted) your LoRaWAN devices source code?


Thanks!

Hello @asergaz ,

Thank you very much for your fast reply.

  1. Yes, by TTN I mean The Things Network where our sensors are registered.

  2. No, at the moment the data is stored on the physical servers. Here is the point. To avoid the maintance of the servers, we are planning to go to the cloud. We are very flexible with respect to a cloud solution / architecture and can consider all options. What important for us is how fast we can migrate and, of course, the price of the solution.

Could you please comment on the proposed above architecture? What would be your suggestion? Talking about IoT Hub, is it an inevitable component for any solution, or do we simple get some advantages by using it (if so, which ones)?

Thanks in advance!

Hello @TetianaLavrenko-3216 (great project ahead :) ). Thanks for the clarification!

To your described scenario and specially because:

What important for us is how fast we can migrate and, of course, the price of the solution.

I would definitely advise you use Azure IoT Central Device Bridge to integrate with The Things Network and an Azure IoT Central application to persist data, visualize it and control devices.

As per the blog post here: The Things Network and Azure IoT connect LoRaWAN devices
"The combination of both solutions, integrated in a matter of minutes, allows you to ingest The Things Network devices and sensors’ data into Azure IoT Central to be displayed, analyzed, and trigger actions in business applications."

See also this great blog post from @SandervandeVelde42 : Azure IoT Central bridge for The Things Network

I hope I could help you get started with your migration to the cloud :).

Thank you!
