What is fog calculation? What is the relationship with the Internet of Things?

Internet of Things Introduction

The Internet of Things is an important part of the new generation of information technology and an important stage of development in the era of "informatization." Its English name is: "Internet of things (IoT)". As the name suggests, the Internet of Things is the Internet connected to things. This has two meanings:

First, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet;

Second, the user end extends and expands between any item and item, and exchanges information and communication, that is, the object meets. The Internet of Things is widely used in the convergence of networks through communication-aware technologies such as intelligent sensing, identification technology and pervasive computing. It is also called the third wave of the development of the world information industry after computers and the Internet. The Internet of Things is the application expansion of the Internet. It is not so much that the Internet of Things is a network, but the Internet of Things is a business and application. Therefore, application innovation is the core of the development of the Internet of Things. Innovation 2.0, with user experience as the core, is the soul of the development of the Internet of Things.

Introduction to fog calculation

Fog CompuTIng, in which data, (data) processing, and applications are concentrated in devices at the edge of the network, rather than being stored almost entirely in the cloud, is an extension of cloud computing (Cloud CompuTIng), Cisco (Cisco) proposed. This name for "cloud" and "fog" comes from the phrase "fog is a cloud closer to the ground."

Fog calculations are as vivid as cloud computing. The clouds float in the sky, high above, out of reach, deliberately abstract; and fog is realistic, close to the ground, right next to you and me. Fog calculations are not made up of powerful servers, but are composed of functional computers with weaker performance and more dispersion. They are infiltrated into factories, automobiles, electrical appliances, street lamps and various materials in people's material life.

The concept of fog calculation was proposed in 2011 and was defined in detail in 2012. Just like cloud computing, fog calculations are also very well defined. The clouds are high in the sky, very abstract, and the fog is close to the ground, with you and me. Fog calculations have no powerful computing power, only a few weak, scattered computing devices.

Fog computing is a distributed collaboration architecture that manages the most effective locations for the specific data sources and services between the actual data source and the cloud. This type of computing is effectively extending cloud computing capabilities and services to the boundaries of the network, leveraging its strengths and capabilities to the point where data can be executed and operated.

Main goal of fog calculation

The main goal of fog is to improve efficiency and to resolve the network traffic jam that may occur when transmitting to the cloud for computing and storage. It is usually designed to increase the efficiency of the entire program, but it can also be used to improve security and compliance.
