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. There is quite the gap between 2 trillion and 14 trillion U.S. dollars….

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.

That stance is…

Internet of Things or Thing on the Internet?

Terminology that loosely ring-fences a group of related technologies is often very helpful in engineering discussions – until the hype machine gets a hold of them. “Cloud” is a fairly obvious victim of this.

Push vs. Pull

Here’s from my Channel 9 Subscribe blog, an ad-hoc, single-take whiteboard discussion on “push” and “pull” communication patterns. There’s a lot of talk in the industry on push (see push notifications) and pulling/polling (long polling vs. web sockets and messaging), so I’m dissecting that space a bit and explore push vs. pull and various pattern…

About the ‘D’ in ACID Transactions

I just got prompted to write this in an email reply and I think it’s worth sharing. My personal definition for ACID’s Durability tenet is as follows: “The outcome of the transaction outlasts the transaction, meaning that the result of the transaction is published to other consumers as the transaction completes. ‘I’ resolves into ‘D’.”…
