We utilize NR in production with 1000s of remote nodes. In order to manage this complexity we built a system that we call Nebula. With Nebula we solved many of the major concerns with production deployment. Security, OTA upgrades, SD card degradation, run-time monitoring, etc. all utilizing a dashboard to manage the deployments.
You can take a look at Nebula here www.iotobox.com
We are looking for people who want to beta test Nebula for us.
For clarity, I am the founder of iotobox.
