Cloud computing-digital resources similar to water and electricity

In the near future, people in addition to pay water, electricity, gas costs, may also be scheduled to pay "cloud computing fees." Why is that? What is "cloud computing"? What are the effects on our lives? We ask the Dean and Professor Lo Junzhou of the Computer College of Southeast University to interpret for everyone.

Cloud Computing is a business computing model, the concept was first introduced by Google in 2006, the core idea is to be a large number of network-connected resources for unified management, forming a pool of shared resources (including computing facilities, storage equipment, applications, etc.), and to pay on demand, Provide services to users in a flexible and extensible manner. This service can be a basic it resource (such as computing power, storage space, etc.) or software or Internet applications. In this architecture, a resource-providing network is called a "cloud", at which point the computer's hardware, software, and data can be moved to the Internet, and users can use the cloud anytime, anywhere, through any networked display device, regardless of the cloud's internal structure and cloud computing processes. Imagine a scene: Mr. Wang in Nanjing is going to Beijing for a meeting, he is ready to show the slides in his home in Nanjing, and then save them to the "cloud"; on the train to Beijing, Mr. Wang felt the slides needed modification, so he logged into the cloud through his mobile browser, It is easy to use the editing software in the cloud environment to update the slides; in Beijing, Mr. Wang connected the computer to the "cloud", opened the slides and successfully completed the report. Throughout the process, Mr. Wang did not have to carry a bulky laptop, do not need to copy data, and even do not have to install any slide editing software, only need to be able to network of monitors.

with the maturing of cloud computing technology and the gradual expansion of application scope, the future cloud computing will be greatly developed:

The diversification of the way cloud computing access. With the rising of mobile terminals and the maturing of IoT technology, the extension of cloud computing will be greatly enriched. In the future, any networked terminal device can access the cloud environment at any time, any location, to obtain the services and resources required.

The diversity of content in cloud computing services. With the increasing demand for cloud computing and the diversification of access patterns, cloud computing will provide users with diversified services and will have far-reaching impact on many areas. For traditional It areas, such as Google and Amazon and other large internet companies will be in the cloud environment integration of more computer resources, when almost all systems, applications and data can be moved to the "cloud", the total liberation of ordinary users and enterprises and institutions.

In the field of scientific research, as the computing power available to the cloud environment becomes more powerful, more and more large scientific computing applications (such as DNA sequencing, meteorological modelling, etc.) will be deployed to the cloud environment. By then, using the massive resources integrated in the cloud environment, this large scientific computing applicationThe line time will be greatly reduced (possibly from a few months in traditional mode to just a few hours or even a few minutes), thus greatly shortening the cycle of scientific research.

In the field of industrial manufacturing, a manufacturing service support platform can be established in the future to support the transformation of manufacturing enterprises from a single supplier to a total solution provider and system integrator, providing services such as information sharing, automatic management of manufacturing processes, and greatly promoting manufacturing automation and globalization.

In People's Daily life, cloud computing will also play a very important role. In the future, every household electrical appliance can even clouds the environment. In this way, people sitting in the office, can also be very convenient for each of the household appliances remote control. At the same time, home appliances can access more users ' habits and other information through even clouds environment, and work together to provide more intelligent and comfortable living environment. In addition, cloud computing will be integrated into education, health and other fields.

With the advent of the cloud computing era, with the development of cloud computing technology and the gradual expansion of the scope of application, cloud computing will be the future of the user's work model and business model of the fundamental changes, at the same time, this change would affect all aspects of life, and greatly improve social productivity, Finally promote the rapid development of human economy.

Cloud computing, let our society develop rapidly

So, what is the difference between cloud computing and traditional computing patterns? In traditional computing mode, people usually need to buy and install specific application software to process working documents, store data, send email, share information, etc. and "cloud" brings is such a change people only need to connect to the "cloud" through the browser can use the "cloud" resources to do all of these operations. The shift is akin to switching from an ancient single generator to a centralized power supply model. It means that the computer resources can also be used as a commodity circulation, people in the use of a number of units of CPU, bandwidth and even the overall packaging of IT resources, that is, to pay "cloud fee", like gas, water, electricity, such as easy access. We do not need to let our computer software and hardware constantly upgrade, as long as the connection with the Cloud computing center, can meet the demand.

The advent of cloud computing has spawned a series of new applications, such as Izumo storage, Cloud TV, and cloud Antivirus, which bring many conveniences to people's lives. Take cloud storage, it is like a hard disk, through the Internet to connect to the user's mobile phone, laptop, desktop and other devices, users can store data at any time on this hard disk, to achieve data synchronization and sharing, without fear of hard disk capacity or data loss and so on. Using cloud storage technology, people can always take photos taken in the "cloud" through the Internet, while the family only connect to the "cloud", open the corresponding partition of the cloud storage, you can immediately check these photos, ready to share the journey happy.

In addition to individual users, cloud computing also brings new information models to enterprises, especially small and medium-sized enterprises. In the traditional mode, enterprises in the information process in addition to the need to build computer rooms, purchase and deployment of enterprise management software, but also in equipment upgrades, hardware and software maintenance, personnel training and other aspects of investment in a large number of human and material resources. In the cloud computing mode, the enterprise information management platform is hosted by the cloud computing service provider, and users can use the daily financial management, customer relationship management, E-commerce and other services on a pay-as-you-go basis. This model not only shortens the information construction period, but also greatly reduces the enterprise's it operation and maintenance cost, and then strengthens the enterprise's market competitiveness.

Use the "cloud"

as if using electricity. At present, the development of cloud computing in our country attaches great importance to the State Council in the "decision to accelerate the cultivation and development of strategic emerging industries" clearly pointed out to "promote the development of cloud computing and demonstration Applications"; , Hangzhou, Wuxi and other 5 cities first to carry out cloud computing innovation and development pilot demonstration work; The Ministry of Science and Technology plans to build "China cloud" during the "Twelve-Five" period. In recent years, China has accumulated valuable experience in the design and manufacture of high-performance computer, developed a "Tianhe", such as a number of international leading supercomputers, this is the Cloud computing data centerThe construction provides the necessary technical guarantee. At the same time, China's massive data storage and processing technology is also very concerned about, "973", "863" and other national science and technology programs will be massive data storage and processing as the focus of research. According to the key technologies of cloud computing, universities have also carried out in-depth research. Among them, Southeast University invested 16 million yuan to build a cloud computing data center; its massive data storage technology was applied to the AMS-02 project, led by Nobel laureate Professor Ting, to store scientific data that grew at a 170tb/-year pace; Its commitment to the national Science and Technology Support Program project will be a large amount of data processing technology used in regional medical and health information processing, to provide accurate and efficient medical services. These related research and application have laid a solid theoretical foundation for the development of cloud computing. In addition, with the rapid development of new Internet applications such as search engine, e-commerce, social platform and so on, many IT companies have established their own data centers, developed and deployed the processing platform, and accumulated valuable practical experience for the development of cloud computing.
