editors note: Check out recent AI Trends Webinar: AI Gets Edgy: How New Chips and Code are Pushing Artificial Intelligence from the Centralized Cloud Out to Network Nodes
As the Internet of Things evolves into the Internet of Everything and expands its reach into virtually every domain, high-speed data processing, analytics and shorter response times are becoming more necessary than ever. Meeting these requirements is somewhat problematic through the current centralized, cloud-based model powering IoT systems, but can be made possible through fog computing, a decentralized architectural pattern that brings computing resources and application services closer to the edge, the most logical and efficient spot in the continuum between the data source and the cloud.
The term fog computing, coined by Cisco, refers to the need for bringing the advantages and power of cloud computing closer to where the data is being generated and acted upon. Fog computing reduces the amount of data that is transferred to the cloud for processing and analysis, while also improving security, a major concern in the IoT industry.
Here is how transitioning from the cloud to the fog can help deal with the current and future challenges of the IoT industry.
