Cloud Computing: What is fog computing?

Grazed from ThoughtsOnCloud. Author: Ahmed Banafa.

The term “fog computing” or “edge computing” means that rather than hosting and working from a centralized cloud, fog systems operate on network ends. It is a term for placing some processes and resources at the edge of the cloud, instead of establishing channels for cloud storage and utilization.

fog computingFog 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)…

Fog Computing extends the cloud computing paradigm to the edge of the network to address applications and services that do not fit the paradigm of the cloud due to technical and infrastructure limitation including:

• Applications that require very low and predictable latency
• Geographically distributed applications
• Fast mobile applications
• Large-scale distributed control systems…
