What an utter load of tripe
So, how exactly does this connect to the cloud when I am in any of:
1. London Underground or other sub-way with nearly non-existent mobile coverage.
2. Out in the sticks with no coverage (>10% of Europe is not covered - covering mountains to 100% is nearly impossible).
3. Standing in the middle of a crowd on a London station concourse when the trains are suspended and everyone is yapping on their phone bringing the Liverpool Stret/King's Cross/Insrt Your Name Here net to 100% capacity. Ditto for traffic jams. Ever tried to get data on a motorway in the middle of a 10 mile tailback?
The idea of "IoT device reported to the cloud and cloud produced an alarm" in a health context is a rank raving lunacy. Real world is not the Silly valley. YOU MAY NOT HAVE A DATA CONNECTION (I am saying that as someone who used to architect cellular equipment for 7 years).
Now long term trends, correlation, prediction, etc - that is a different story. It is indeed in the big data/map reduce/machine learning domains - stuff cloud does best. But definitely not "your blood sugar dropped, you got an alarm". That is idiotic to the extreme. A system trying to do that in real life will kill half of its diabetics under observation even before the first lawyer says the words class action suit.
