Fog Computing Distributing Data and Intelligence for Resiliency and Scale Necessary for IoT

Fog can provide intelligent connection of people, processes, data, and things in hierarchical Internet of Things networks and by supplementing the cloud and providing intermediate layers of computation, networking, and storage, fog nodes can optimize IoE deployments---greatly enhancing latency, bandwidth, reliability, security, and overall IoE network performance.

Abstract

The Internet of Everything (IoE) is more than a $19 trillion opportunity over 10 years. Fifty billions of devices will be connected to various networks in 2020. This is bringing new technical challenges in all domains and specifically in the data processing. Distributed intelligence is one of the key technological answers. We call it "fog computing." Fog can provide intelligent connection of people, processes, data, and things in hierarchical Internet of Things networks. By supplementing the cloud and providing intermediate layers of computation, networking, and storage, fog nodes can optimize IoE deployments---greatly enhancing latency, bandwidth, reliability, security, and overall IoE network performance. The article will analyze the architecture and main design choices of this technology.
