The Truth About Cloud computing: Limited network bandwidth allows "fog computing" to help

Cloud computing may be an important force for change, but an article on the Wall Street Journal, "Forgetting Clouds" and "fog" is the future of technology, points out that "fog computing" may lead to real computational change due to the proliferation of Access devices and limited network bandwidth.

The following is the full text:

Smartphones have been exploring and absorbing data, but without the help of cloud computing, smartphones are no doubt impossible. Because no enterprise service can store its own data in someone else's data center.

Advocates have a preference for cloud computing, which they believe will have a full cloud in the future. Many technology companies are selling cloud services to consumers in such a guise. In fact, importing and exporting data from the cloud is far more difficult than the engineers or managers admit.

Cloud truth: The more device access, the worse the bandwidth

The first problem is bandwidth. If companies are struggling to cut down on the cost of storing data, the cloud will be a better choice than sending data back and forth through high-speed cables. But by magnifying the scale of the world, people need to get information from their mobile devices, bandwidth is stretched. All businesses that need to send data to mobile devices, including airline booking services and business data for salespeople, are gaming the bandwidth limit.

According to 9374.html > World Economic Forum Data, the United States ranked 35th in the world for the bandwidth per user. Mobile applications become the main way for people to handle transactions on the network, the equipment itself has a certain amount of data processing capabilities.

As people become more and more reliant on cloud computing, devices are becoming more intelligent, and the challenge before us becomes to work beautifully so that people can have unrestricted office space anytime, anywhere. From aircraft engines to refrigerators, smart devices are pushing things online into people's lives.

From the cloud to mobile device data transfer process, the current 3G and 4G network is still not fast enough, as the Internet era more devices to access the network, the situation will become worse.

Fog end: To make the device to form a conveyor belt

Thankfully, there are solutions: no more sticking to cloud computing, and studying how to store and process their own data on IoT devices, or between devices, on the web.

Cisco has an interesting name for the phenomenon: fog calculations (fog computing). As with cloud computing, fog computing is also very image-like. Clouds drift high in the sky, very abstract, and the fog is close to the ground, right beside you and me. It has no powerful computing equipment, only weaker, more decentralized computers, dealing with data on appliances, automobiles, street lights and other devices.

Cisco's main router, which is perhaps the most boring business in the field of technology except storage. To create a compelling selling point for itself, Cisco wants to turn routers into hubs-gathering data and deciding how to handle the data. In Cisco's view, smart routers interact with the cloud only in Birburd situations, such as warning of emergency situations.

IBM is also developing similar functionality, and they are pushing computing to the edge. The so-called boundary Computing (Edge computing), literally understood, is the boundary between the Internet and the real world. The data center is the center of the network, with PCs, mobile phones and surveillance cameras on the border.

Just as the cloud is made up of server clusters, in IBM's project, the "Fog End" is made up of devices around us. We can have one device send an upgrade packet to another device without networking.

We have too much data and this is just the beginning. Take the aircraft, for example, a new Boeing 747 access to the Internet, record, in some cases, send a state data stream. In a single voyage, GE says, an engine produces more than half a byte (terabyte) of data.

Cheap sensors produce a lot of valuable "big" data. Through predictive analysis, companies such as General Electric (GE) can learn which parts of the engine may need repairs before the plane lands.

If that's not the case, why do you think the tech giants like Google and Facebook always talk about other alternatives to Internet access, such as balloons, drones, etc.? The current operators did not complete the work. Only when the fast wireless, wired network coverage sufficient, computing equipment close enough to the user, the Internet of things can play a role.

The future of enterprise computing is still in the cloud, but the real computing change of the future will happen here, beside you and me-not in the clouds, in the mist.
