What the heck is Fog Computing?

While many are still trying to figure out Cloud Computing, here comes a rival concept – Fog Computing. It’s computing that takes place at the edge of the network, closer to home. That is, computing that takes place on the devices that are nearest to you – your smartphone and other connected devices that are around you. The so-called Internet of Things (IoT), or Internet of Everything (IoE).

Fog Computing is not a new concept. Like Cloud Computing, it’s just a marketing buzzword for something that’s already taking place. Here’s an excerpt from a Wall Street Journal on the topic:

The problem of how to get things done when we’re dependent on the cloud is becoming all the more acute as more and more objects become “smart,” or able to sense their environments, connect to the Internet, and even receive commands remotely. Everything from jet engines to refrigerators is being pushed onto wireless networks and joining the “Internet of Things.”

Modern 3G and 4G cellular networks simply aren’t fast enough to transmit data from devices to the cloud at the pace it is generated, and as every mundane object at home and at work gets in on this game, it’s only going to get worse.

Luckily there’s an obvious solution: Stop focusing on the cloud, and start figuring out how to store and process the torrent of data being generated by the Internet of Things (also known as the industrial Internet) on the things themselves, or on devices that sit between our things and the Internet.

Marketers at Cisco Systems Inc. CSCO +0.79% have already come up with a name for this phenomenon: fog computing.
