Who can tell me when the era of cloud computing began? Why is it called cloud computing?

In a narrow sense, cloud computing refers to the delivery and use of IT infrastructure, and refers to obtaining the required resources in an on-demand and scalable way through the network; Cloud computing in a broad sense refers to the delivery and use of services, and refers to obtaining the required services in an on-demand and extensible way through the network. The service can be related to IT and software, Internet or other services. The core idea of cloud computing is to manage and schedule a large number of computing resources connected through the network in a unified way to form a computing resource pool and provide users with on-demand services. A network that provides resources is called a "cloud". The resources in the "cloud" can be infinitely expanded by users, and can be obtained at any time, used on demand, expanded at any time, and paid according to use. The industry of cloud computing is divided into three levels: cloud software, cloud platform and cloud device.

Development history

1983, Sun Microsystems proposed that "the network is the computer". In March 2006, Amazon launched Elastic Computing Cloud (Elastic Computing Cloud; EC2) service. On August 9th, 2006, Eric Schmidt, CEO of Google, first proposed the concept of "cloud computing" at SES San Jose 2006. Google's "cloud computing" originated from the "Google 10 1" project of Google engineer Christopher Bisciglia. From June 5438 to October 2007 10, Google and IBM began to promote cloud computing programs in American university campuses, including Carnegie Mellon University, Massachusetts Institute of Technology, Stanford University, University of California at Berkeley and University of Maryland. This plan hopes to reduce the cost of distributed computing technology in academic research. And provide related hardware and software equipment and technical support for these universities (including hundreds of personal computers and BladeCenter and System x servers, these computing platforms will provide 1600 processors and support open source platforms including Linux, Xen and Hadoop). Students can make various research plans based on large-scale computing through the network. On June 30th, 2008, at 65438, Google announced the launch of the "Cloud Computing Academic Plan" in Taiwan Province Province, which will cooperate with Taiwan Province National Taiwan University, Jiaotong University and other schools to promote this advanced large-scale and fast computing technology to the campus. On July 29th, 2008, Yahoo, Hewlett-Packard and Intel announced a joint research plan covering the United States, Germany and Singapore, and launched a cloud computing research test bed to promote cloud computing. The plan is to create six data centers with partners as research and experimental platforms, and each data center is equipped with 1400 to 4000 processors. These partners include Singapore Information and Communication Development Agency, Steinbuch Computing Center of Karlsruhe University, University of Illinois at Champion, Intel Research Institute, HP Labs and Yahoo. On August 3, 2008, the information on the website of the United States Patent and Trademark Office showed that Dell was applying for the trademark of "cloud computing" to strengthen the possible reshaping of this technology in the future. 20 10 On March 5th, Novell and CSA jointly announced a vendor-neutral plan called Trusted Cloud Plan. 20 10 in July, NASA and other supporting vendors including Rackspace, AMD, Intel and Dell announced the "OpenStack" open source plan. In June, 20 10, Microsoft expressed its support for the integration of OpenStack and Windows Server 2008 R2. Ubuntu added OpenStack in version 1 1.04. 2011February, Cisco system officially joined OpenStack, focusing on developing OpenStack's network services.
