Closer to the Edge

Edge computing is all about moving computing capability to a variety of devices enabling users to perform a variety of activities when and where they need it. Most often, edge computing is interpreted to mean mobile devices, but it could just as easily be your refrigerator, your television, your entertainment system, your mobile phone, or the various systems in your automobile.

Much of edge computing is already in place, it is just not obvious. For example, the Tivo used to track, schedule, record, and playback television programming is nothing more than a media center computer that has been programmed to record broadcast programming. In this context, the AppleTV is nothing more than an alternative programming computer tied to the television. The Slingbox is another programming device that captures video and streams that video to a variety of devices--from your TV to your computer, to your mobile phone. In these examples, the device is a server providing services to edge devices.

Another is the OnStar system in your automobile. Through this system, your car's performance can be tracked, your doors unlocked, or automatic alerts can be sent to a centralized monitoring center. X10 and similar technology provides monitoring of your house, enabling you to remotely turn on and off lights, set alarms, and control edge devices such as a television or appliance. In these example, the device is a monitoring and control unit providing manipulation and control over remote devices.

All of this edge technology is available now. Add to this the ability to view television programming on mobile phones (VCast, SprintTV, MobiTV, YouTube, and the increasing number of streaming videos available on Web sites); the ability to listen to audio programming through tools such as iRadio and streaming sites on broadcast Web sites; and the increasing number of sites that enable word processing, spreadsheet manipulation, and presentation development (Google Apps is a primary example). All of these are providing expanded access to computing by any device that can access those sites and capabilities.

As a result, computing is no longer limited to the desktop or the laptop computer. Today, browsing the Web can be accomplished on your phone and your game console. Word processing can be accomplished on any device that accesses the Web. Is the computer dead? Not by a long shot. However, its central importance in information management is being reduced as processing is delivered through the Web and access and control devices become more incorporated into edge devices. We are moving closer to the edge.
