Distributed Cloud Computing<br />
Fog Forecast<br />
Centralized, or cloud, computing has solved lots of problems but it<br />
has also created a few new ones of its own. By moving out to the<br />
edge and closer to the source of the data, computing systems will<br />
be much better suited to absorb the coming data tsunami and<br />
assist in bringing about the Tactile Internet of tomorrow.<br />

Ever heard of Fog Computing?<br />
If not, you are in good company<br />
because most people<br />
haven’t the foggiest idea<br />
either. Nonetheless, it is probably<br />
one of the hottest IT trends in recent<br />
years. The basic idea is simple: Move<br />
your centralized cloud structures<br />
closer to the data on the fringe of<br />
the network. This concept is called<br />
Edge Cloud and has been around<br />
for years. In June <strong>2018</strong> the OpenFog<br />
Consortium published the OpenFog<br />
Reference Architecture which was<br />
immediately adopted as an international<br />
guideline to meet the data-intensive<br />
requirements of the Internet<br />
of Things.<br />
“We now have a ... blueprint that will<br />
supercharge the development of new<br />
applications and business models,”<br />
says Helder Antunes, chairman of the<br />
OpenFog Consortium and senior director<br />
at Cisco, the network company<br />
that provided the reference model.<br />
“We are constantly wasting time and<br />
bandwidth by transferring all the data<br />
gathered by our IoT devices first to the<br />
cloud for processing and then moving<br />
the results back into the network.”<br />
It would be much more sensible, he<br />
believes, to do most of the processing<br />
on the network’s edge where the data<br />
resides. Of course, this calls for some<br />
pretty fancy routing – but intelligent<br />
routers are what Cisco does.<br />
It also means that the networks themselves<br />
need to get smarter and a<br />
broad consortium of manufacturers,<br />
from Google to Apache and Dockers,<br />
are on board this push towards<br />
the edge. They are joined by mobility<br />
experts who have incorporated Fog<br />
into the blueprint for the emerging<br />
5G wireless standards. Despite the<br />
wireless community’s interest, Fog is<br />
actually based on wired data processing<br />
but, here, the new motto is: “Less<br />
centralism, more distribution of tasks”.<br />
Central computer systems are prone<br />
to overloadd. That was one reason<br />
Protecting Data through Fog<br />
companies began switching to PCs in<br />
the 1980s, each operating as a central<br />
server on the department level and<br />
connected through a client-server<br />
architecture. Sometime around the<br />
mid-2000s the whole idea was turned<br />
around when virtualization of servers<br />
made it possible to centralize<br />
computing power once more, which<br />
saved a ton of money but didn’t really<br />
solve the bottleneck problem – in<br />
fact, it made it worse.<br />
Centralization has its obvious uses,<br />
of course. You get to store all your<br />
data at a convenient single location<br />
where you have it under control and<br />
can process it anytime you want.<br />
■ GDPR<br />
The newly enacted European General Data<br />
Protection Regulation (GDPR) is expected to<br />
become a major driver for fog, or distributed<br />
cloud computing. Authorities in Europe are<br />
tasked with overseeing the use of personal<br />
information at the local level and non-compliance<br />
can lead to heavy fines. Edge computing<br />
could provide a foolproof way of making<br />
sure sensitive data is stored and processed<br />
within the territorial limits of the European<br />
Union, as stipulated by the new regulation.<br />
