Re: [iot-wg] Integrating Eclipse IoT projects

Just to follow up on this, we started work on a Hono device registry based on Elasticsearch. I hope to share more info on this in the coming days, so that we can involve more people in it. But as Jens said, everyone is welcome to join the call tomorrow and community in general.

Hi Bob,

it is great to see your interest in Hono and EnMasse. I think we have similar issues, but we are also currently working on it. :)

Of course our goal is to make OKD, EnMasse and Hono play nicely together. And we also are looking for a scalable device registry. And some easy to use integration between the kubernetes world and EnMasse+Hono.

I would like to carefully point you towards our "iot" branch in the EnMasse repository: https://github.com/EnMasseProject/enmasse/tree/feature/iot

Please note, this is an experimental, and not very cleaned up, branch of EnMasse, which adds Hono to the EnMasse deployment on OKD. In a nutshell we want to:

* Deploy a single EnMasse "infrastructure" instance
* Proxy the communication from the protocol adapters towards different EnMasse addresses/addressspaces â to support different EnMasse tenants
* Let users use a custom resource called "IoTProject" to define a Hono Tenant
* Implement the Tenant Service which is backed by the custom resource "IoTProject"
* Create an operator, which manages the EnMasse messaging resources (if requested)
* Implement a scalable (general purpose) device registry, which implements the credentials and registration API of Hono

Most things are already working to some degree. But for the device registry, we are currently in a very, very early stage. However the idea is to bring in this device registry to the Hono project itself. So that others can re-use this and join in ;-)

If you plan to try this out, please bring some patience. As I mentioned, this is a work in progress, in a very early stage, and every now and then, thing may be broken in this experimental branch. But of course I would be happy to help you if you want to give it a try.

I think it would make sense if you would join the Hono community call, IIRC the next one is tomorrow: https://www.eclipse.org/hono/community/get-in-touch/#project-call

Cheers

Jens

Hi Kai,

It's nice to see this call. We, atÂAloxy, are currently moving towards a more secure, scalable, performant and future proof IoT backend application. We have a great interest in all Eclipse IoT projects, especially the ones for the backend since we already have device and gateway software which is really customized towards our application. We already started integrating and currently we have connected Eclipse Hono with Eclipse Ditto. Everything runs on OKD and enMasse is used as the messaging framework. We still have following challenges ahead:

  • Implement a production worthy auth service for Eclipse Hono.
  • Implement a production worthy device registry service for Eclipse Hono.
  • Implement a front-end to manage:
    • Tenants
    • Devices
    • Credentials
  • Create one place where everything is configured. Currently we have to configure a tenant in Eclipse Ditto as well as in Eclipse Hono (and afterwards maybe even in Kapua as well, although we probably won't use it if this is the case). It would be nice to have one configuration service/database. This would greatly reduce the configuration effort.
Â

We didn't have a thorough look into Eclipse Kapua yet but maybe Eclipse Kapua help us tackling (some of) the described challenges.

We are happy to discuss this and test functionality if we can. We might even contribute depending on the occasion.


Kind regards,

Dear IoT Working Group members,

during the working group's meeting at last year's EclipseCon Europe in
Ludwigsburg, the Eclipse Kapua folks told us about the efforts of integrating
Eclipse Hono with Kapua in order to use Hono as an alternative to Kapua's default
device integration layer. During the meeting we agreed that it would be helpful
for users to better understand, which technologies/projects are related and could
be used together in order to implement certain use cases.

As part of this endeavor, we would like to continue our work on integrating Hono
with Kapua, but more importantly, we would also like to discover new
opportunities to create more value by integrating some of the (other) Eclipse IoT
projects with each other. This is where you come into play. Have you already
thought about trying to use one of the other Eclipse IoT projects with the
project you are involved in? Can you think about a "better together" scenario but
haven't found the time (or collaborators) to start the integration work yet? Then
it would be great if you could share your ideas with us on the mailing list.

Based on your feedback and ideas, we would like to set up a face-to-face "kick-
off" meeting for the next integration round (probably hosted by Bosch Software
Innovations in Berlin in March).

Looking forward to hearing your ideas :-)
