Why is it called the origin of cloud computing?

It is called "cloud computing" because it has the characteristics of real clouds in some aspects: clouds are generally large; The scale of cloud can be scaled dynamically, and its boundary is fuzzy; The cloud is erratic in the air, and you can't and don't need to determine its specific location, but it does exist somewhere.

It is also called "Cloud" because Amazon, one of the founders of cloud computing, adopted a new name "Elastic Computing Cloud" (EC2) for what was once called grid computing, and it has achieved commercial success. Cloud computing is regarded by its touts as a "revolutionary computing model" because it enables supercomputing power to circulate freely through the Internet. Enterprises and individual users no longer need to invest in expensive hardware acquisition costs, but only need to purchase rental computing power through the Internet. "Use your computer as an access port and leave everything to the Internet." Users only need 640K memory. "Bill Gates said in 1989 about" the past, present and future tense of computer science ". At that time, all the programs were very small, and the 100MB hard disk was almost inexhaustible. Internet is still being developed in the laboratory, and hypertext protocol has just been put forward. Their widespread application will begin in six years. At present (2008), such information can be retrieved from the website that provides installation services. A standard computer that an ordinary white-collar worker needs is a low-end Core Dual-Core/1GB memory/100GB hard disk. Soon, megabit hard disks will enter the range of home computers. Behind the rapid development of hardware configuration is the rapid growth of data on the Internet, which is simply challenging the limits of human imagination. When massive data was put forward as a concept, the unit was GB. Now this is just a data unit of a small website.
