How to run Azure IoT Suite a few days more (before running out of Azure credits)

Microsoft provides a great IoT platform on Microsoft Azure. And next to the resources (IoTHub, StreamAnalytics, etc.) available on Azure, Microsoft also offers a great introduction named Azure IoT Suite. and they are very serious about it!

To be clear, The IoT Suites are not complete solutions to be used as-is or even to be sold as-is. They have to be handled as a reference architecture… Use them to get started, use them to demonstrate the capabilities of the Azure IoT platform or use them as a piece of discussion for your future solution. Microsoft even helps you by providing the inner logic as open source. So you can extend it yourself. And they even show some examples on how to extend these suites.

At this moment, there are three preconfigured solutions:

  1. Remote Monitoring
  2. Predictive Maintenance
  3. Connected Factory

These are all three great solutions. There are simulated devices and you can add your own devices too. For example, the Connected Factory can connect to real devices using the OPC technology.

Note: For now, Predictive Maintenance and Connected Factory are out of scope for this article.

But there is one issue: it’s ‘expensive’. For example, this is what’s generated for the Remote Monitoring example:

  • 1 Azure Active Directory application
  • 1 IoT Hub (S2 – Standard tier)
  • 1 DocumentDB Account (S1)
  • 2 Event Hubs (Basic throughput unit)
  • 1 Storage account (Standard-GRS)
  • 3 Stream Analytics jobs (1 streaming unit per job)
  • 1 Azure App Service Web App for Website (P1 – Premium: 2 small)
  • 1 Azure App Service Web App for Web jobs (S1 – Standard: 2 small) running 25 simulated devices by default

Here are some examples. The S2 IoT Hub itself costs 421 euros. The two App Service Plans behind the web services consume 250 euros together. And there are three Stream Analytics jobs, each will cost 75 euros.

So if you demonstrate or test this IoT Suite, you can burn your MSDN account in a couple of days. Is it possible to change this?

So here is a collection of easy changes you can do yourself on this particular Predictive maintenance IoT Suite.

The IoT Hub can run as good on an S1 and it costs only 42 euros. That’s a cost reduction of 350+ euros or more than ten euros per day. With the steps below, you can reduce the total costs to fifteen euros or so per day…
