Fog Computing Aims to Reduce Processing Burden of Cloud System. Fog computing is bringing data processing, networking, storage and analytics closer to the devices and applications that are working at the network’s edge. Cisco Systems officials have spent much of the year talking about extending the cloud with “the fog.” In January, the networking giant introduced its fog computing vision, the idea of bringing cloud computing capabilities—from applications and data analytics to processing, networking and storage—to the edge of the network, closer to the rapidly growing number of user devices that are consuming cloud services and generating the increasingly massive amount of data. Cisco officials also unveiled the company’s IOx platform, designed to bring distributed computing to the network edge. Cloud adoption will only grow in the future, according to Todd Baker, head of IOx product management at Cisco. As it does, the fog’s importance will grow as well.“We really see the cloud and fog as complementary to each other”. To be sure, Cisco may have coined the term “fog computing,” but the company is far from the only tech vendor embracing the idea of putting compute capabilities out to the infrastructure edge.
Fog computing tackles an important problem in cloud computing, namely, reducing the need for bandwidth by not sending every bit of information over cloud channels, and instead aggregating it at certain access points. This type of distributed strategy lowers costs and improves efficiencies. More interestingly, it’s one approach to dealing with the emerging concept of Internet of Things (IoT).
