The wind of cloud service to the campus a variety of services to the present

In the field of education, more clear "cloud services" than "cloud computing". He said that in the cloud computing concept, more is the computing resources, the platform, is the research route. And cloud services is from the user needs, to provide users with technical support, providing services, this is two different routes.

The wind of cloud service blows to the campus

"Cloud computing should be a shift in the way the service works, and it comes from the green of the data center." "said Ziqiang, a researcher at the Academy of Sciences Acoustics. He believes that only "public", cloud computing can get out of the "parrot" misunderstanding, "to establish a common infrastructure, the use of large-scale to reduce costs, adapt to business needs on demand." ”

In the industry, one of the most successful example is the SME informatization. One of the most important things Alibaba has done is to help SMEs export. Everyone can open shop in Taobao, but its most important and most popular reason is the enterprise management of small and medium-sized enterprises. Aliyun through SaaS (Softwareasaservice) way, can provide SMEs with CRM, ERP and other services, small and medium-sized enterprises do not need to build their own room, but also with the management of large enterprises to connect.

Coincidentally, China's higher Education document security system Calis, also tends to more small and medium-sized libraries to provide cloud services platform. This is the first large-scale use of cloud computing for schools to provide services to the institutions.

Since 2008, Calis has launched a new generation of interlibrary and document delivery systems that support SaaS (ie, SaaS version), supporting distributed "cloud" Service Calis Digital Library Cloud Platform (Caliseasycloudplatform) and a range of other cloud application systems. March 2009, Calis Cloud service test water set sail, first in Tianjin to establish Calis Cloud service center, for Tianjin University Library to provide Calis interlibrary loan and document delivery system SaaS service.

Using the Calis Cloud service platform, Calis built a two-level cloud service center to support building and sharing, while providing a local digital library solution based on a "hybrid cloud". These centers and member pavilions collaborate and integrate with each other to form a nationwide network of digital library services.

"Small and medium-sized libraries are spadger, spite, but to enter the digital library era, the need for a large number of funds and human support, the biggest problem is the scarcity of technical personnel, cloud service platform can make them exempt from these concerns, with very low cost, directly with the digital library era." "Wenqing said.

A reader needs the library does not have the publication, may first inquires to the Calis head, through the literature transmission network, may submit own request to the school library, may also directly to have this literature the library submits the request to obtain. Even, we can get the corresponding service through the reference Service platform of literature and the platform of searching and borrowing. The Calis dispatching center can automatically find the most suitable documents for readers according to the type of document request and the service cost, service quality and collection scope of each service hall.

The digital campus not only needs custom traditional service, but also needs to integrate many services to meet the uncertain needs of school teachers and students. Sun Yat-sen University Guo Qingshong that there will be more services in the future, he said: "The core business of the school is the production of knowledge and knowledge consumption, cloud services will be integrated campus and outside the campus to break through the logic wall." "On its platform, it will be better to meet the consumption of knowledge, so that teachers and students easy access to knowledge, at the same time, through the computing platform and resource platform for synergistic interaction, production of new knowledge."

Liu, director of the Institute of Digital Library, Shanghai Library, also believes that the library can either enjoy cloud services or serve as a provider of cloud services. "Cloud services provide storage, platform, and computing power to libraries, while libraries use cloud services to handle business and greatly reduce the cost of library information technology input." Through the use of a unified management platform for all types of resources and formats, sharing applications and data to achieve greater network benefits. ”

Blending and presenting of various services

As Professor Li Shing said, "The real implication of the cloud lies in the transformation of service patterns", many schools have written cloud services to the upcoming "Twelve-Five plan", or have carried out practical practice, with a view to using new technology to integrate services, making educational resources more efficient and convenient.

Sun Yat-sen University will soon carry out its "cloud service Portal" construction, according to Guo Qingshong, the major has contacted the relevant service providers, platform providers to purchase the relevant cloud services, at the same time, personalized information for individual users will be integrated to provide storage management services, school teachers and students will be able to on this platform, Establish a personal information center, Knowledge Base, document resource base, etc.

In addition, the company will also work with Lenovo, Shuguang, and other cooperation, to provide students with virtualization technology, free to provide students with a cloud terminal, students can purchase related services, at any time on the need to switch their desktop environment.

"Storage bandwidth and other resources are on the one hand and, more importantly, business services." As a cloud service platform, only PAAs, IaaS and other hardware environment services is not enough, must enter the application-level services. Calis chief Engineer Wenqing said.

Cloud service platform is a great impetus to the traditional business of library, and the effect is direct and obvious. During the "XV" period, Calis began to deploy interlibrary loan system, because of the need for hardware environment, technical personnel and business personnel to equip and support, the cost is quite high, after several years of efforts to participate in the museum to reach more than 100, and once the formation of cloud service platform, the rapid development and expansion of the system.

On the Calis platform, there is a "tourism colleges" of the five-Star Alliance, is from Shandong, Jilin and other four tourism institutions of the library to form a virtual shared domain, with a common sharing mechanism, can realize interlibrary loan and resource sharing, and establish a unique personalized shared domain portal.

"These four pavilions only took a few days to complete the construction of the virtual shared domain and its service platform." At present, we can provide such services to 1800 university libraries, and during the ' Twelve-Five ' period, I believe that more than 2,400 museums will be able to enjoy such services. ”

The convergence and integration of services across the pavilion and across domains is one of the most concerned goals of Calis and a major innovation. Wenqing Introduction, in the cloud service platform mode, future library some traditional business, such as automatic system cataloging, circulation management, interview management, and more related technologies, will break the physical library boundaries, can be outsourced and implemented in the cloud platform, and the library will be able to focus on the quality of content to work, Integration of more services to the service-oriented library transformation.

Liu Baisong, a deputy curator of Ningbo University, suggested that when building the regional Digital Library cloud service platform, it was based on the infrastructure services IaaS and the infrastructure platform services PAAs to provide library-oriented digital library service integration platform, using an open architecture, so that different library local services, regional DL public services, Integration of industry public services and third-party public services.

Shared domain, area cloud, private cloud, various concepts, the most important point is to provide services to groups with the same characteristics.

Since 2009, Lanzhou University has started to build the "private cloud" of campus, in which the integration of the three services has become the goal.

First, to provide a unified content services, hope to be compatible with the campus network of all services. Second, provide storage services. Third, the integration of operational capabilities. According to this idea, they have made the consummation to each concrete aspect construction. In the content output service, changes the traditional website content output model, unifies the plan according to the cloud idea.

They adhere to the "content of the King", first, the integration and presentation of content. Second, to do the push service, they feel can not hope that the traditional content published online for everyone to browse, it is necessary to push the important content out. They use Coremail to push a lot of information to teachers and students.

It is proposed in the information Twelve-Five plan of Zhejiang University that the application service integration platform based on SOA will be set up to transition to cloud service and build a unified, open and shared Application service support platform.

Similar actions are underway. Relevant sources said that the campus network should be based on the principle of pragmatism, do not regard cloud services as research and experimentation, so must use sophisticated technology. "Must form an open structure." Can not only use one or two products, can not be kidnapped by one or two of products. ”
