Sending data between device and a module running in EFLOW about iotedge-eflow HOT 3 CLOSED

ok.. I've been reading more (and noticed issue #3 is a similar question that I have). If I wanted to share modules and was willing to setup the internal networking properly on my Hyper-V to the EFLOW vm, what do you think of using something like IIS to serve files to modules. I Don't think it makes sense to support WebDAV adn davfs2 in teh EFLOW vm... but I could build an HTTP client into my module to pull/push data to the host os. It doesn't feel to elegant to me tbh. But it's a thought. (I'm getting some push back from team members on creating anykind of device agent to interop with modules).

Thanks!

I've been a little slow getting back to you due to a forthcoming change that we have coming in the Azure EFLOW implementation that will remove the ability to use Hyper-V Manager to configure the VM. This architectural change will lay some groundwork for us to provide support for GPU inside the VM enabling AI/ML scenarios.

• Would you be interested if we could provide the ability to share a folder on the Windows host with the Linux VM that you could access your log files directly from your module?
• In addition to using the leaf device approach as explained by our samples on http://aka.ms/winiotsamples (soon to be moved over to this repository), it is also possible to use socket communication, but you would also need an agent to act as the sender and your module implemented as a listener.
• IIS does sound like an alternative.
• Have you thought about using the SQL Edge module with Azure EFLOW?

Hi Terry (@TerryWarwick),

Thanks for taking the time to respond! I'd be interested in learning more about the GPU support you mention (Is there anywhere you talk about it? ). Our Win 10 IOT Enterprise device has a very expensive graphics card in it.

I think we would be interested in the Share a folder approach for a couple of reasons. Our device acquires some pretty dense medical imagery (sometimes 100s of GB) and being able to make these files avaialble to modules supports some of our longer term road map plans. Of course the next question is, what is your timeline for the share a folder? Days? Months? Quarters? (I don't need an exact date more a general one)

I will look into SQL Edge to see how it works (I haven't yet). Would it replace the SQL install we already have? that'd be interesting.

THanks for responding!

All my best!
