I've been kind of wondering what the business case for "internet of things" is for years, and now I realize. It's a modern SCADA. No more, no less.

- xenophonf 12y agoAccording to this article, IoT has the same security guarantees as SCADA, too.

- jfoutz 12y agoThere are a few different parts. I keep thinking about amazon, facebook and google's programmable infrastructures. Control needs to be secure, but data acquisition could be public. I can imagine a gas company that supports surge pricing like uber. If all this stuff is visible as a web service, you can take a regular old programmer and optimize inventory and delivery schedules. I'm sure that happens now, but i'm not sure how sophisticated it is. There's probably some value in a car being able to access the octane rating and price of gas on fillup, which would update your phone with price and performance metrics. I think there's also an aspect of service discovery you're overlooking. I guess the point is, the words "internet of things" are goofy and overused, but it implies being more pervasive, open and standardized than scada.
- HeyLaughingBoy 12y agoKinda. It's S(CA)DA where each node can have its own TCP connection instead of being RS232, Modbus, etc and then aggregated over TCP through a device server. Basically facilitated by cheap Ethernet hardware. e.g., I have a BeagleBone monitoring a mousetrap in my basement. Total cost about $60; would be half that with a Raspberry Pi. It's only on my internal network, but it would be trivial to put its webpage online or serve up the data to something like what Pachube used to be.
