Delight in Thinking

Cloud computing is not a technical nature, but a new mode of information processing and transmission. It can be defined from different perspectives cloud computing, such as technical support from the point of view, cloud computing is an important technical support for virtualization technology, virtual technology can be achieved through the sharing of computing resources, virtual technology is not a new technology, its development can be traced back to the early stages of computer technology, especially in the mainframe - terminal mode, the number of terminals can use the same host of computing and storage resources. Later developed to the client - server model, the client has its own computing power for the local treatment, while the server data. The emergence of the Internet has changed the mode of the computer network, in particular the emergence of Web, making the client - server model has become more simple and clear, the formation of the browser - server model. This model can be said that the embryonic form of cloud computing.

Cloud computing is accompanied by development of the Internet to form a new computing model, the model is based on the network, use the word cloud of this romantic mode to name this calculation, it is entirely from the network, People often use the network cloud icon to indicate when the cloud paint more and more, icons, system structures almost always have to draw clouds to represent the Internet, the cloud would be independent, to form a specific pattern, This model is called Cloud Computing.

Cloud Computing is a fundamentally Internet model, in this mode, the entire Internet into a supercomputer, it can be done by the supercomputer most computing tasks to realize the information processing and transmission, which is cloud. When the Internet became a super computer, people's computing model is complete a cycle, that is calculated back to the original model - Zhuji model, that Internet users are using a computer, which is virtual technology as a support Zhezhong computing model of core technology. Virtual technology is a complete multi-level architecture, including hardware layer, the platform layer, application layer level, including the completion of a computation, to achieve all the components of computer applications. The core of this architecture is how to integrate the various components to form a complete independent system. So, what is the adhesive bonding of various components? The answer is simple: service.

Service became the core of cloud computing, the cloud model, all are services. Infrastructure into a service that iaas; platform into a service that paas; software into a service that saas. If we extend this concept to the general level, that is xaas. Therefore, cloud computing is a basic equation:

Cloud computing = XaaS, all are service!

Here, we need an explanation of the services in the cloud computing model, the service has a broader meaning, it not only refers to the system to provide the services and, in a sense, more importantly, the system and systems of services, that all the services are services, including services to users, including system services, in other words, both human services, including service on the machine. When we establish a cloud computing service that all basic equations are after, then Renhe Yun computing is the process of solution of this equation,

Application of our library of cloud computing is the process of solution of this equation, if we will build in the cloud model of library service called Cloud library, then the cloud library can be expressed with this formula:

Cloud library = LaaS, that cloud is the library as a library service.

In the context of cloud computing, the library as a service consists of four aspects of meaning:

1. Library is a Web-based information services, libraries should be drawn 应用 System icon inside of Clouds. In other words, the library should be a cloud;
2. Library network to provide information services to end users, that cloud is a network of libraries should exist;
3. Library system through the network information service, which goes into a large library exists in the network database, other applications can be seamless integration of library information;
4. Library system and other systems should be seamless to integrate access to other resources.

In the cloud computing environment, the library service as a kind of information and knowledge-based infrastructure, the cloud computing model is a function of layer architecture, the library is a ubiquitous cloud.

Debate between technology and humanity is very boring, because it is well aware that should not be controversial. Areas such as business studies, the emergence of electronic commerce by business studies in hot pursuit, not seen what people say service is the first of the exclusive e-commerce. Technology extends the service, which is not discussed, the success of e-business shows a very simple truth, that is in the Internet age, any service can only structure on the strong technical support. Library Services, of course can not be an exception. But it is a lot of the library community, "smart people" do not see these, do not know if this is "smart people" or the library community sad sad. Some people also plausibly play the "Library is the institutional arrangements," the slogan that I have to ask what social institutions are not institutional arrangements? If anything, what arrangements library, then there is no doubt that the library is a technical arrangement.
Some people may not opposed to technology, heart and even agree that the importance of technology, they are only opposed to "technical rescue plan", and they feared they would be excluded from the technology loop, unable to participate in a grand plan to save the cause of such concern very cute, but not necessary. Technical rescue plan is not a matter of several technical experts, but all librarians do. Xiamen University has a very great institutional innovation - "balls." "Balls" cause I do not know, but the "balls" all those who love the museum's entire focus on the development of young people concerned about libraries, regardless of what position they are, what background, IT experts, Ye Hao, cataloging experts Ye Hao, Circulation of library assistants or whatever, can join the "balls", "balls" as a cross-sectoral, multi-disciplinary, technology as the core business areas related to the entire library of technical innovation team, to bring together books Museum of technology building blocks, a library technology innovation engine, idea database, and I think this should be the Xiamen University Library in the field of technological development led the industry in the important reasons. Mechanism of rice balls, not only in Xiamen University library, but we can at the Shanghai Library, Peking University Library, Shanghai Jiaotong University Library and other large library to see the shadow of rice balls, these libraries are all technology leader. Rice ball is a great mechanism for innovation in this mechanism, each person can put a library to the library of technical innovation and the development of the flood, how exciting it is? Those who oppose the rescue plan technical people, why not get rid of the burden into the torrent to this?
Technical rescue plan is something all librarians, not just technical experts of things, but technical experts put the figure in the technology undoubtedly played an important role. However, the library of technical experts been marginalized public library community, library of technical experts as the world enjoy high-wage high-status, our technical experts been marginalized, this is not normal. I remember, and "technical rescue plan" put forward the slogan author to discuss the reason, he deeply marginalized for library technology sector concerned, technical department have a lot of talents, to carry out important functions, they should be more concern and attention, play a greater role. I am sure he is right is for the library's future development vision. This is what I have spared no effort "technology to save map" beating the drums of reasons.
In fact, like me, an ordinary librarian, can only be none other than the edge of a hand shouting numerous refueling only, sometimes crying out of the throat, were you one with a set of all the offset. I can do is be a clown just forwarding you laugh, and you have to have a much bigger role, which is why I suddenly want to write this letter to you.
Professor Cheng, your generation is worthy of respect and library scientists, because of your drum-banging and hard practice, our library from a bureaucratic institution-oriented services into a service-oriented social institutions, it is 30 years, the library has undergone a revolutionary leap, you Laohuai so humble, this generation of library scientists in the crowd are our idol. Service was in the library's survival and continued development of the foundation, we are deeply identified with the idea of your services, but services and technologies are not contradictory, emphasizing technology services is not necessary to exclude the cost of the rapid development of modern technology today , services and technology are inseparable in fact, technology that is service, service, technology, we can not separately to each other. Technology development is always beyond one's imagination, but also contrary to people's feelings, I know you have a deep love of books that will give you great joy scholarly, but technology is changing, times are changing, we The new generation of users is no longer emotionally attached to books, so that they no longer intoxicated is scholarly, but the mouse Titicaca sound. How do we do? We can not put Confucius used bamboo spread on the table, forcing the young man after reading, we can not treat addiction as as electric shock readers do not read. The only thing we can do is to change our service model, our services into their familiar environment to go, this is the basic concept of technical rescue plan. Professor Cheng, Professor of you as a librarian and a director of a large academic libraries should be able to resonate.
Professor Cheng, you may look down on technical drinkers, even you may look down on modern technology, but live in a technological world, you may be unable to avoid the technology, since technology can not be avoided, why not refuel for the technical applause? Maybe you another point of another position, contribution to the development of the technology would be enormous.
Technology exploration is a painful process, lonely process is under great pressure of the process, technology drinkers not only have the intelligence, more should have strong willpower. In my mind, these strong library technology explorers is a hero. I can not become a member of them, but would like to applaud them, but also urge Zhubozhaizhu to where we are cheerleaders, we were together cheering for the technical drinkers. Ok?
