What is the concept of cloud computing?
The origin of cloud computing is controversial, and two main schools of thought prevail. The most widely accepted view is that Eric Schmidt, the former CEO of Google, was the first to propose the concept of "cloud computing (Cloud Computing)" at the search engine conference in 2006. However, some believe that Amazon in the United States is the pioneer in the field of cloud computing because it was the first to launch the Elastic Compute Cloud (EC2) service and is a promoter in this field. The theoretical origin of cloud computing can be traced back to the world's first electronic computer, ENIAC. Early computers like ENIAC were expensive, huge in size, and lacked multi - user capabilities, so people had to queue up to use them. In 1955, John McCarthy proposed the time - sharing technology concept. In the same year, Christopher Strachey proposed the concept of virtualization in an academic paper. In 1961, John McCarthy proposed the concept of Utility Computing. Although the basic technologies related to cloud computing emerged one after another, from the 1970s to the 1980s, people were mainly focused on the software and network in the booming PC market and ignored Utility Computing. In 1984, John Gage proposed the important conjecture that "the network is the computer", which described the new trend of distributed computing technology. Cloud computing is actually a form of distributed computing. In the 1990s, the related concept returned to people's vision under the name of grid computing. In 1996, a group of technical directors of Compaq first used the term "Cloud Computing". Cloud computing aims to better manage resources. It virtualizes and integrates various IT resources such as computing, storage, and network into a service. There are three cloud models: public cloud, private cloud, and hybrid cloud. Public cloud is provided by third - party providers and can be accessed via the Internet, allowing users to share basic computer infrastructure. Private cloud is built for a single customer, providing the most effective control over data, security, and service quality. Hybrid cloud is a combination of public and private cloud services. There are also three cloud computing services: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). IaaS is at the bottom layer, providing computer infrastructure services for users. PaaS is mainly for developers and is in the middle layer. SaaS delivers software applications to users, and users can use network - based software by paying rent without buying and installing software locally. Read more exciting novels for free
Harmony between Heaven and Man
The following are some lyrics related to "Harmony between Heaven and Man": " The beautiful fate of mountains and rivers has been passed down for thousands of years. Thousands of years of poetry and books, thousands of miles of beautiful flowers, a beautiful moon, and a beautiful flower are even better than heaven and earth. The harmony between heaven and man is endless. Through the ages, loyalty and filial piety are passed down. The elegant hall is made of green bamboo, and the tile-roofed houses and willows are connected into romantic scenes. My lovely city, this is my most beautiful home. My lovely city, you are the source of my love. The harmony between heaven and man is infinite. Through the ages, loyalty and filial piety have been passed down. The sound of water trumpets, dreams of childhood, and the sincere wish made in front of Pengzu Mountain." <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
