IoT Challenged but Growing
Author: Chris Adams, President and CEO, Park Place Technologies.
No sooner have we accepted IoT than innovations are transforming how this hyperconnected world will be implemented. Among the emerging technologies is fog computing, which moves computing closer to the end-user to decrease latency and bandwidth overload while improving access.
The fog network architecture taps client and/or edge devices to handle much of the demands of IoT. As such, fog computing peels away from central cloud storage, backbone networks, and network gateways. It is inherently decentralised, distributing compute cycles wherever they can increase efficiency, so less volume and more refined data is transmitted.
There are many benefits to fog computing in the emerging IoT landscape. It can drive:
- Reductions in data volumes sent to the cloud
- Network resource savings
- Latency decreases
- Improved data access times
As with any technology, fogging has its challenges as well:
- Fog devices are new, and there aren’t many choices yet. Quality has not caught up with the concept.
- Any fog device exists on the LAN and must be managed. A plethora of them can make for network administration headaches.
- Security isn’t wholly buttoned up. Fog computing is vulnerable to man-in-the-middle attacks and remote authentication schemes, not to mention new physical security problems caused by its distributed nature.
At this point, the industry is sure about IoT—it’s here and it’s expanding. Nonetheless, given the need to solve the data volume transmission problem, the IoT future is definitely foggy.
