Industry observation: where will IT go if cloud computing is used?

Article title: industry observation: where will IT go if cloud computing is used. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

"The user only needs KB of memory ." Bill Gates talked about the past, present, and future of computer science in 1989. At that time, all the programs were very small, and MB hard disks were useless. The Internet is still being developed in the lab, and hypertext protocols have just been proposed. Their wide application will begin six years later.

Today, you can find this information on the website that provides the installation service. The standard computer for a common white-collar worker is: low-end core dual-core/1 GB memory/GB hard drive, very fast, the MB-level hard disk will be used by the home machine.

Behind the rapid growth of hardware configurations is the rapid growth of data on the Internet, which is simply challenging the limits of human imagination. when massive data is proposed as a concept, it is measured in GB. Now, this is only the unit of data size for a small website. If one day, the data available on the Internet is 1000 times or more, what will our PC look like? What kind of hardware will evolve? Or does a personal computer have to handle such massive data computing?

Cloud computing provides another possibility.

Cloud computing is an emerging business computing model. The high-speed Internet transmission capability is used to move the data processing process from a personal computer or server to a computer cluster on the Internet. These computers are common industrial standard servers managed by a large data processing center. The data center allocates computing resources based on customer needs to achieve the same effect as the supercomputer.

"Cloud" is a metaphor for computers with a network distribution, and also refers to the hiding of the data computing process, where the server depends on your needs, "carved" the one you need from the big cloud. It is a very romantic metaphor.

High-performance low-cost PK security risk warning

Cloud computing is regarded as a "revolutionary computing model" as it makes it possible for Super Computing to flow freely through the Internet. Enterprises and individual users do not need to invest any more in expensive hardware purchase costs. they only need to purchase rental computing power over the Internet. "use your computer as an access port and give everything to Internet cafes ".

Imagine that mobile devices with smaller sizes and lighter sizes can handle more powerful computing power without being limited by local hardware. We can run the most demanding online game on a thin and thin paper notebook, or access Photoshop online on our mobile phone to edit and process the photos we have just taken.

What's more attractive is that enterprises can get extremely high computing power at a very low cost, instead of buying expensive hardware equipment to carry out frequent maintenance and upgrades. For example, the US real estate website Goosipy.com wants to build a database that calculates the data of 0.67 million families who have bought and sold their houses in the past 12 years, so as to provide consumers with better suggestions. If they do it on their own, it will initially take six months and millions of dollars.

Finally, they rented the "elastic computer cloud" service provided by Amazon.com. by using Amazon's powerful data analysis capabilities, it took only three weeks to complete the project, cost less than $50 thousand-one of the highlights of cloud computing is the ability to make full use of the performance of large computer clusters in a pay-as-you-go computing model. If you only need to use 5% of the resources, you only need to pay 5% of the price, instead of paying for 100% of the devices as before.
