Getting sensor, meter and PLC data to the commercial clouds / IoT platforms has required some tinkering with intermediate servers and conversions. There has not been a direct route from the sensor to a cloud database. There is now.

Further, you're able to add your own applications or bespoke communication to the edge. Check this out.
