The new application of cloud computing in campus education field

The need for campus cloud computing

With the rapid development of information technology, computer technology has become a necessary auxiliary tool in every school, especially in colleges and universities. Computer to bring convenience, but also bring people to use the trouble, the need to use computer services units and individuals are often not computer professionals, the lack of experience on computer technology, the school departments are relatively independent of each other, resources are relatively independent, if they independently deploy the required computer services system, Will result in a serious waste of resources.

In schools, the information systems of different departments are different, but the operating platform is similar, if you can establish a unified shared infrastructure platform, then the departments only by deploying their own applications on the virtual platform, the backend platform to the Cloud Computing center processing, which will greatly simplify the cumbersome and maintenance of user deployment complexity, It also improves resource utilization, and departments need not buy hardware and software to deploy stand-alone applications.

Research projects, some of which need to be calculated on High-performance computing servers to produce the expected results. High-performance computing systems are expensive, expensive, and complex to run, and it is unrealistic for each required department or project to establish its own high-performance computing system. Therefore, through the unified establishment of High-performance computing platform in the whole school, and to provide users with the way of cloud computing, can greatly improve the utilization of the system and can be centralized management and application statistics.

The campus implementation of cloud computing

Based on the analysis of campus cloud computing needs, we can build a unified cloud computing center on campus, build infrastructure cloud, public platform cloud and high-performance computing cloud to meet the needs of campus cloud computing. The only difference is that this model is not a complete business model, but a "free" service model.

Infrastructure Cloud

Infrastructure, that is, hardware facilities, mainly including server systems and storage systems, the use of virtualization technology, the centralized server system and storage system as a unified infrastructure cloud, through the service model of IaaS to provide campus units to use.

The South University of South DellPowerEdgeR905 uses hardware facilities such as a server and vmwarevsphere to build the infrastructure cloud. R905 is a Dell Rack server with strong performance and virtualization benefits and is ideal for infrastructure virtualization platforms. With R905 virtualization advantages and powerful IO performance and extension capabilities, the infrastructure platform is built through virtualized suite vmwarevsphere, which builds multiple virtual machines for faculty and department users, each of which can establish more than 10 virtual machines with single virtual processors and dual virtual processors , the virtual machine is running well, without hardware resource delay, the user can use the virtual machine as a stand-alone server in a transparent situation, and give full play to the performance and utilization of the server.

Public Platform Cloud

The common platform, the application running platform, mainly includes middleware, Web server and database service. Through the virtualization technology of such software, build a unified public platform, provided to users through PAAs, users need to apply to the Central Management Center middleware Virtual Services, web hosting and the corresponding database virtual space, which can be deployed on top of their applications, users do not need to build these platforms themselves, Save the cost of input and operation maintenance.

High Performance Computing Cloud

High-performance computing cloud, high performance computing platform, mainly includes server and storage hardware, high-performance computing management platform and Common and common computing software and math library running on platform.

By deploying the common High-performance computing platform hardware throughout the entire school, by building a high-performance computing platform on top of the management software and installing the computational software and math libraries needed for general scientific computing, and so on, through SaaS delivery to the needs of the users, users simply submit their jobs through a unified submission portal, And based on the number of resources allocated by the Management center, and after the completion of the operation to obtain the required results. In this way, the high performance computing resources can be centrally managed, and the computing customers do not need to know their internal architecture and technology, that is, they can perform the various operations needed to greatly improve the utilization of resources and the ease of use of the system.

With rocks as the main high-performance computing management system, the South University of South University of South and South University has built high-performance computing systems with different processor architectures for Dell and other PC servers, and deployed the software system that needs to be run on the corresponding high performance computing units to achieve high performance computing.

Cloud computing is the emerging computing and service model of the IT world, which frees end users from cumbersome use and maintenance of computer systems, allowing users to easily use a variety of computer services. At the same time, the limited resources will be concentrated to provide unlimited services, greatly improving the utilization of resources. The university's computer service needs are extensive, and the end-users of each unit have limited computer skills, which is extremely inconvenient to the use and maintenance of the computer, and because of the limited resources of the campus, it is urgent to improve the utilization ratio. University of this kind of demand, just can pass the advanced cloud computing model to perfect realization, so by building the campus cloud to meet the campus computer service demand, is undoubtedly an effective way and reasonable scheme.
