2 trillion (Gartner), 4 trillion (ARC), 7 trillion (IDC, PwC), 14 trillion (Cisco), 19 trillion (SoftTech). U.S. Dollars. Cumulative value-add by “IoT”. by 2020. or 2022. or 2025. or over the next 20 years. Shiny CFO and potential investor eyes. Because dough.

Internet of Things – Terminals, Hosts, Peripherals

[This is a follow-up post to “Internet of Things or Thing on the Internet?”] The metaphor “Internet of Things” stands for the next wave of expansion of scope for distributed systems.

“Service Assisted Communication” for Connected Devices

There is good reason to be worried about the “Internet of Things” on current course and trajectory. Both the IT industry as well as manufacturers of “smart products” seem to look at connected special-purpose devices and sensors as a mere variation of the information technology assets like servers, PCs, tablets, or phones. That stance is…

Mobile, Outside, Inside, and Attached: A Taxonomy for Mobile Experiences

We’re talking a lot about “Mobile” solutions in the industry, but the umbrella that this moniker casts has become far too big to be useful and doesn’t represent any particular scenario subset that’s useful for planning services for “mobile” devices. Nearly every personal computing scenario that consumers encounter today is “mobile”. This post is a…

Internet of Things: Is VPN a False Friend?

“Internet of Things” (IoT) is the grand catchphrase for network-enabling everyday objects and leveraging the new connectivity to collect information from the devices, allowing network-side control, and supplying information to those objects that allows them to do new tricks – like telling a toaster about the day’s weather forecast so that it can burn a…
