[[MISC-TN-005: Running AWS Greengrass Core on SBCSPG_Running_AWS_Greengrass_Core_on_SBCSPG|This]] and [[SBCX-TN-003: Deploying modules to Azure IoT Edge_Deploying_modules_to_Azure_IoT_Edge-enabled SBCX with Visual Studio Codeenabled_SBCX_with_Visual_Studio_Code|this]] Technical Note show how to connect two different DAVE Embedded Systems products to famous IoT cloud platforms, Amazon AWS and Microsoft Azure, respectively.

MISC-TN-006 will show instead how to implement an Industrial IoT system by following a different approach. In this case, we will be using open-source software stacks both on the edge device and on the cloud platformwill be used. This choice is extremely flexible and allows making use of implementing on-premise cloud infrastructure as well.

For the sake of simplicity, Kapua platform was installed on a desktop PC running Debian Stretch distribution. The procedure is described [http://www.opensourcerers.org/connecting-kura-to-kapua/ here] and it is quite straightforward, as it is based on the use of a Docker container.The following log shows how to start Kapua:  <pre class="board-terminal">sysadmin@linuxbox:~/devel/kapua/kapua/deployment/docker/unix$ ./docker-deploy.shDeploying Eclipse Kapua...compose_events-broker_1 is up-to-datecompose_es_1 is up-to-dateStarting compose_db_1 ... doneStarting compose_broker_1 ... doneStarting compose_kapua-console_1 ... doneStarting compose_kapua-api_1 ... doneDeploying Eclipse Kapua... DONE!Run "docker-compose -f /home/sysadmin/devel/kapua/kapua/deployment/docker/unix/../compose/docker-compose.yml logs -f" for container logs</pre>

The installation procedure of Kura framework on the edge device is pretty straightforward as well. Again, please refer to [http://www.opensourcerers.org/connecting-kura-to-kapua/ this document] for more details. In this example, the ''Device Display-Name'' field was customized as follows:

To run a simple demo to test for uploading data to the cloud, the following steps can be carried out:*Creating a new Cloud Connection

*Installing and configuring the example publisher applicationavailable [https://marketplace.eclipse.org/content/example-publisher-eclipse-kura-4xyhere]. The procedure is described [https://eclipse.github.io/kura/cloud-api/2-user-guide.html here]. Unlike the linked document, however, a new cloud connection was not created and the existing one was used instead. The resulting Publisher configuration looks like this:  [[File:Kura-publisher.png|thumb|center|600px|Configuration of the publisher]]    After installing the publisher package by dragging and dropping the Eclipse Marketplace link into the Kura Packages section, it was configured as shown in the following image.  [[File:Kura-publisher-example-application.png|thumb|center|600px|Configuration of the example publisher application]]    If everything was set up properly, every second the example publisher application will upload new data to the Kapua platform. This is visible in the log file on the SBCSPG device ...
