Fog computing, also known as fog or nebulization, is a decentralized computing infrastructure in which data, calculation, storage and applications are distributed in the most logical and efficient place between the data source and the cloud. Cloud computing essentially extends cloud computing and services to the edge of the network, bringing the advantages and power of the cloud to where data is created and acted upon.
The tarnishing goal is to improve efficiency and reduce the amount of data transported to the cloud for processing, analysis and storage. This is often done to improve efficiency, although it can also be used for safety and compliance reasons.
Popular cloud computing applications include smart grids, smart cities, smart buildings, vehicle networks, and software-defined networks. The fog of metaphor comes from the meteorological term for a cloud near the ground, just as the fog is concentrated at the edge of the net. The term is often associated with Cisco; The company's product line manager, Ginny Nichols, is believed to have coined term. "Cisco Fog Computing" is a registered name; Cloud computing is open to the wider community. The Open Fog Consortium was founded in November 2015 by members of Cisco, Dell, Intel, Microsoft, ARM and Princeton University; Its mission is to develop an open reference architecture and convey the commercial value of cloud computing.
How the Fog Works
Although edge devices and sensors are where data is generated and collected, they do not have the computing and storage resources to perform advanced machine learning and analysis tasks. Although cloud servers have the power to do this, they are often too far away to process data and respond in a timely manner. In addition, having all endpoints connected and sending raw data to the cloud over the Internet can have privacy, security and legal implications, especially when it comes to sensitive data subject to regulations in different countries. In a mist environment, processing takes place in a data concentrator on an intelligent device, or on a smart router or gateway, thus reducing the amount of data sent to the cloud. It is important to note that the fog complements and does not replace cloud computing; The fogging allows short term analytical analyzes at the edge and the cloud performs long term analytical analyzes that require many resources.
