Delight in Thinking

Cloud computing is not a technical nature, but a new mode of information processing and transmission. People can be defined from different angles, cloud computing, such as from Technical Support point of view, cloud computing is an important technical support of virtual technology, virtual technology can be achieved through the calculation of resource sharing, virtual technology is not a new technology, Its development dates back to early computer technology, particularly in the host - the terminal mode, the number of terminals can simultaneously use the same host of Jisuan and storage resources. Later developed to the client - server model, the client has its own computing power for local processing, while the server data. Emergence of the Internet to change the mode of computer networks, in particular the emergence yes Web, allows customers to client - server model has become more simple and clear, forming a browse device - 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 term cloud computing in 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, the icon structure of application systems almost always have to draw to represent the Internet cloud, cloud to be independent, forming 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 Le a cycle, returns to the original calculation mode - host mode, the Internet, its users live to use a computer, Zhe is a virtual technology as a Zhichengzhezhong computing model of core technology. Virtual technology is a complete multi-level architecture, including hardware layer, platform layer, application layer level, contains complete a calculation, all the components by 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 the service, which paas; software into services 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 user 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 computing model known as cloud Library Services under the Library, then the cloud libraries can use this formula to express:

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 web-based information services, libraries should be drawn in the application icon inside the cloud. 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 into a knowledge-based information and infrastructure, cloud computing model of the whole structure of a functional layer is an omnipresent cloud library.

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. Jishu De develop and extend the service, this is not the discussion, e-commerce's success means its a very simple truth, that Jiu Shi Zai Internet age, 任何 service only structure on top of powerful 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 might not opposed to technology, heart and even agree that the importance of technology, they are only opposed to "technical rescue plans", and they feared they would be excluded from the technology loop, unable to participate in a grand rescue plans cause worry about it 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" I do not know the cause, 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, stressed the service is not necessary to exclude technology Dai Jia, Zai fast developing modern technology , 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, contribute to the technological development will 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?

This topic is very luxurious, encompasses many of the current hot area of information technology terms, from Web2.0 to cloud computing, these terms constitute a bright Web world from the past into the future road map.

The life cycle network around the world is a stage of ten years, from the first generation Web experiences to Web2.0 about 10 years, 10 years, Web address of the person's interaction with the network problems, from Web1.0 only provides user information to facilitate the development of reading networks to provide interactive Web2.0 Wei Channel, From, Web is not just a media, but rather an Xianghugoutong of information Jiaohuan platform. In the Web2.0 environment, users do not just Web-readers, but also Web content providers and participants, today, Web2.0 basic Web has matured and become mainstream. Web2.0 site full of large networks, and nurture a large number of users, it can be said, Web2. Really fostered the rise of a virtual network society.

W eb2.0 A key feature is involved, that Web users can participate in Web content development. This is a surface feature, in this feature is the technical architecture behind the changes, Web1.0 is a page mainly Goucheng, and by Web2.0, HTML is no longer a Web of Jichu, but to apply 系统, particularly those being Chen of the content management system (CMS) for Web applications, Web1.0 to Web2.0 development is from the Web Page to Web Application Development Changes.

Changes in the structure of this kind of technology changed the basic properties of networks, Web is no longer an isolated one of the sites together through networking, Er Shi Ying Yong's broad range of integrated Web, Web变成Le Tongguogongneng and content integrated up a Zhengti, into a large system. In order to achieve such integration, Web 环境 Xuyao address system under the mutual communication between, in particular, functional and Shuju the reuse problem, so birth Le Web Service Jia Gou, Zhe Zhong Cheng Wei Web2.0 service-oriented architecture framework for a landmark . Therefore, from a technical architecture perspective, Web2.0 features is the Web Service that network services.

W eb as a large distributed system requires not only open the Web Application services (Web applications), also need to be structured description of data. Described only through the structured data, application systems in order to be understood, in other words, an efficient distributed network applications require the machine to understand the data. If Web2.0 is built on open service framework, so next-generation network will build on this basis, a machine can understand the structured and interrelated with the data environment Once the data environment established, then the Web will enter a new era, this new Web environment, we can call Web3.0.

W eb3.0将to solve is a data of the presentation, making machine can sense of the data structure information, structural information Beichengzhiwei Zhege data semantic message that the Yuyiwangluo need to resolve the core issue can Kan Cheng Yu Yi Wang is Web3.0 start. Semantic Web has experienced a development from concept to reality the process, its technical architecture has become increasingly clear, that is of concern associated with the data (Linked Data). There are two basic points associated data that describe and connect. Description and links are for machine service, the machine can be achieved by describing the automatic discovery and confirmation of the link can support the machine automatically link.

We go back and look at web1.0, 1.0 conditions, visit the device from the server, where access to information, directly displayed on the screen, do not know the meaning of information, web pages and link each other through hyperlinks, but the need to manually click the trigger, 2.0 Automatic combination through the machine to a variety of information, By 3.0, the network Zai data layer on the establishment of the link mechanism, the data structure information is well describing, and to ensure that the machine through the URI 来 Nenggouzidong link a variety of data, Shi Xian intelligent automation of information aggregation.

Then, cloud computing is not the natural effect?
