An IoT hub is a cloud hosted platform responsible for all communications to- and from Nodes. Other on-prem or cloud based services which would benefit from interacting with the Nodes would do so through the IoT hub. support four different IoT hubs from Microsoft, Amazon, Google and IBM. Through this integration, devices and things can be fully managed far beyond what is provided out-of-the-box.

Although IoT hubs in general provide the same basic functionality, the main difference would be what is behind the IoT hub, such as machine lerning, reporting and processing. Your choice of IoT hub would, in the majority of cases, depend on what you want to do with the data.

Amazon AWS IoT - There are billions of devices in homes, factories, oil wells, hospitals, cars, and thousands of other places. With the proliferation of devices, you increasingly need solutions to connect them, and collect, store, and analyze device data.

Get Connection Settings from Google IoT Core

  1. Navigate to Google Cloud Platform, select your project and navigate to the Project settings page.
  2. Form the Project settings page, select Service Accounts from the left-hand menu.
  3. Create a new Service Account and name it “microServiceBus”. The account must have Cloud IoT Owner privileges or higher.

The Cloud IoT Owner privileges are required to browse the registry and manage devices.

  1. In the Service account details page, add a new key using the ADD KEY drop-down list and select Create new key. Select the JSON key type. Save the downloaded file.

The downloaded project credentials file contains secure information. Store it in a safe place!

  1. From the menu, select IoT Core
  2. If you haven’t already created a Registry, click the CREATE REGISTRY button. Give the Registry a name and select a region.
  3. Navigate to the Getting started wizard and click the GET STARTED BUTTON
  4. Fill out the Account and Organization details and hit Next.
  5. In the Configure IoT Hub section, select Google IoT Core
  6. Click the LOAD PROJECT CREDENTIAL FILE and select the file you save in step 4. Continue to set the Registry Id and the Region.
  7. Hit the TEST CONNECTION button to verify the connection.

No IoT Hub

There are scenarios where an IoT hub is not required, or rather required for the microServiceBus Node. For instance, if you have already built a working solution and only require Device Management (OTA, logging, monitoring, vulnerability scan and control), -the “No IoT Hub” option might be best suited for you.
