MyOpenHAB server infrastructure and usage

I am dreaming up a scenario where I would have thousands of devices constantly reporting power usage to a private openHAB cloud instance. I’m trying to imagine what sort of servers and traffic this sort of usage scenario might require.

It got my wondering if anyone might be willing to share some stats related to the myopenHAB instance that is public. ie. numbers of users, how many devices, how much traffic, what sort of resources the server has assigned, size of db, etc. Any thing might be helpful in understanding the scaling of openHAB. Thanks!
