Reading two stories must understand "cloud computing"

This is a really poised concept, since the proposed 6 years, countless words in the interpretation of it, but more than 90% of the readers do not know what "cloud". These words all carry a tone: cloud computing, simply ... Unfortunately, the "simple" words behind, readers still do not understand, IQ seriously frustrated. Please read the following story, I will be sure you can find the confidence of IQ: cloud computing is such a thing.

Story One

The public grid abandoned Edison

Edison's bull is unspeakable, in this life has more than 2000 inventions, in the scientific community he eats more salt than ordinary people eat more food. But it was one of those bulls who had been slapped on the beach: the public grid dumped him mercilessly.

In the 1878, Edison decided to develop a new product-the electric light bulb, in order to continue to give it power, he followed the invention of ammeter, generators, etc., this is a complete set of power supply system: Edison Lighting Company to make bulbs, Edison Electric Company manufacturing generators, Edison wire Company production lines.

However, his products only support DC power plants. A big drawback to direct current is that it cannot be transported over long distances. As a result, more and more individuals and enterprises began to generate electricity independently, to light Edison's DC light bulb. Independent power generation makes small private power plants blossom. Because of the long-term supply of equipment for these plants, Edison founded the General Electric Company took the opportunity to send a big fortune.

However, Edison is a great inventor, but not a shrewd entrepreneur, it believes that direct electricity is the future. The short board was recognized by his admirer, the British thrall: he was more of an AC power. Alternating current can be transported over long distances, with this foundation, a large number of inefficient private power plants can be integrated into a "central power plant", through a wire, electricity can be transported everywhere to use.

But Edison was not bullish on the idea because it would cut off his profits: his business interest was that the more private plants there were, the better his equipment would sell. According to Edison, every business or individual has to own a small power plant. So, in this battle, the Anglo-Thrall, who relied on AC power, won. Through the "Central power Plant", the British thrall to achieve a large-scale public grid.

As a result, companies or individuals that originally built private power plants could avoid the purchase of expensive equipment. They only have to pay, and the plug on the wall provides a steady stream of electricity without caring where the power comes from. The story replaces the "public grid" of private power plants, the "cloud computing" of the electrical age.

Story Two

The birth of information "public grid"

1971, Intel (micro-blogging) company invented the micro-computer. Because of its low price and ability to accomplish a variety of tasks, the micro computer quickly replaces the main computer and becomes the center of the company's computing operations. Since then, the original main computer has been transformed into a private server (a private power station), which is connected to many PCs below.

Edison's light bulbs can only be paired with DC power plants, and these PCs can only use the server's programs. This mode (c/S mode) has been extended to date. Just as every enterprise in the electric age must build a private power plant, every enterprise must now have a private data center.

Private power plants can not achieve long-distance transmission, the server information can only be spread on the local area network. Private power plants are used only by businesses and individuals, and data center information is used only within the enterprise. In February 2005, Google bought 30 acres of land in northern Oregon State to build a huge server technology center. So, the information of the "public grid" appeared, this is "cloud computing."

Here, containing tens of thousands of, or even hundreds of thousands of of cheap CPUs and hard drives of the server, this is the information age of the "Central Power Plant", which is the original Enterprise internal server (private power plant) integrated into a machine centralized processing. Since then, enterprises do not need to purchase expensive equipment, no longer need to cultivate a large technical team. They just have to believe that there is a computer connected to the network, without having to worry about where the data is stored.

"Cloud computing" then quickly came into our lives. YouTube has 800 million independent visitors a month, but it often runs only a few people who hire Amazon's servers to provide services and save a lot of capital investment.

The two stories are highly correlated: wires are equivalent to broadband, light bulbs are computers, and private plants are the equivalent of private servers, and public grids are the equivalent of the current "cloud computing".

Notes

"Cloud computing" that 99% of readers don't understand

The cloud is drifting closer to our lives, but its concept is far from us. I have seen a group of survey data on the internet, more than 90% of readers do not know what "cloud computing". When I took this set of data and told an insider, he replied with disdain: "More than 90%, the real understanding of the estimated less than 1%." ”

He is also obsessed with the "cloud computing" understanding of the obstacles, "too abstract, there is no specific sense of things, so understand the difficulty." "Rongjin also told the author," The concept itself is a very nonsense. "Based on this, the author around to the professionals" to learn from, until someone recommended this "it no longer important."

"Cloud computing" is an impetuous concept that is commercialized much faster than we think. Because of "cloud computing" application, a large number of "cloud Products" were published, which have real goods, there are parallel imports. However, as long as we understand the "cloud computing" concept of the nature, it is clear that the so-called "cloud products", what is it.

Exploration

The double meaning of "cloud computing"

The information "public grid" is only part of the meaning of "cloud computing", from the Carr "it no longer important." There is also a more popular understanding that "all the local things can be put into the cloud to complete is the cloud." ”

The future computer will not need the host, only need a monitor. What happened to the stuff in the chassis? They will all be stored in the cloud. Some gamers are eager to pursue a strong graphics card, CPU, the future of these all do not need, you only need a set of keyboard and mouse and display, you can achieve the desire of "enthusiasts", and the support behind this is "cloud computing."

The information "public grid" only belongs to one aspect of the meaning of "cloud computing". Xiang, a communications observer, argues that the concept of ' cloud computing ' can also be said to be a private power generation, which now has centralized power plants. He says the concept can also be understood as "aggregating the computing and storage capabilities of a large number of computers."

It also has a richer meaning. "The information ' public grid ' is a pseudo concept," Rongjin, a black horse joint initiator. "It mainly says that after all you don't use your own server, it's better to rent someone's server directly." "Cloud computing is the data that we used to store on the hard disk and is now stored directly on the web," he says. ”

Of course, cloud storage is just one of the basic functions of cloud computing. For example, "cloud computing" stores many online games, but these games can be run directly by users without the need for CPU. There is also a more popular understanding that "all the local things can be put into the cloud to complete is the cloud." "Rongjin said.

In fact, the information "public grid" is not Karl's only point of view. In the book he also mentioned that the future of the various parts installed in the computer chassis, through "cloud computing" can be integrated into the Internet, for each user to share. The meaning of this sentence is that the CPU inside the chassis, hard disk, etc. are hanging in the "cloud", the future of the computer only need a monitor mouse button.

I think, "The meaning of cloud computing can also be explained by the information" public grid "theory, which can be seen as a private power station in the personal computer chassis, which will be stored in the" Central power Plant "when the" Central Power Plant "(cloud computing) is used in the future.

"Cloud computing" is a supercomputer, which not only stores countless data and software, but also provides "computing" functionality. It can be the "central server" of the enterprise or the "Central mainframe" of the PC. The combination of two meanings, perhaps to better explain "cloud computing."
