Cloud floor, fog computing is coming-cloud computing, fog calculations-IT news Cloud floor, fog calculations are coming

Fog calculations (Fog Computing) cloud computing (Cloud Computing) extension of concepts by Cisco Systems (Cisco) initiative. The "cloud" and "fog" is named "the cloud fog is close to the ground" in the name.

Fog computing and cloud computing, quite literally. Clouds float in the sky, high above, elusive, deliberately abstract and fog is a reality, and close to the ground, just you and me. Fog calculations are not made up of powerful servers, but by the less powerful, more diffuse kinds of functional computers, into factories, automobiles, electrical appliances, lights and people's living standards in a variety of products.

Compare with cloud computing, the mist is distributed computing architecture used by more, closer to the edge of the network. Fog calculations, data processing and application set data at the network edge devices, rather than almost all of them like a cloud computing in the cloud. More than data storage and processing on a local device, instead of as a server. Therefore, cloud computing is the next generation of centralized computing, while fog calculations is the next generation of distributed computing, Internet-compliant "decentralized" feature.

Fog calculations do not like cloud computing, require users to connect large data centers to remote access services. In addition to the differences in architecture, cloud computing can provide applications, fog computing can provide, just fog calculations used in computing platform performance may not be as large data centers.

Cloud carries the industry's expectations. Industries have generally agreed that future computing power will be completely in the clouds. However, import, export, data from the cloud is actually better than people thought it would be much more complicated and difficult. Due to access devices (especially mobile devices), more and more, at the time of data transmission, access to information, bandwidth becomes stretched. With the rapid development of Internet and mobile Internet, more and more people rely on cloud computing and networking devices more equipment more and more intelligent, mobile application becomes the main way people are processing transactions online, increasing data volumes and the number of data nodes, will not only take up a lot of network bandwidth, but will also increase the burden of data centers, data transmission and access to information the situation will get worse.

Thus, matching fog of distributed computing, by intelligent routers and other equipment and techniques, composition data across different devices, can reduce network traffic and data center computing workloads are correspondingly reduced. Fog can be calculated as M2M (machine-machine dialogue) between cloud computing and network to cope with M2M networks generate vast amounts of data-the use of handlers on the pretreatment of the data, in order to enhance its usefulness.

Fog calculations can not only solve the problem of networking equipment automation, more critical is that it demands for data smaller. Fog calculations that "promote cloud data center inner workings of the technology" helps to improve the local storage and computing power to eliminate bottlenecks in data storage and data transmission, very worth the wait.
