Application model of cloud computing in the construction of scientific research informatization

I. Problems in the construction of scientific research informatization

1, information construction funds need to increase

With the continuous deepening of the information construction of scientific research units, especially after the popularization of the high integration of scientific research information platform, the hardware equipment and technical force of scientific research units are put forward higher requirements, which need to spend a lot of manpower and material resources. And with the rapid development of IT industry and rapidly changing, software and hardware replacement speed, in the course of information construction in the future may even have a hardware system just built, the use of soon faced the embarrassing situation of elimination, making the construction of scientific research information needs more and more funds.

2, the utilization of digital resources is not high

At present, the construction of special network of scientific research units has been basically completed, many units of network bandwidth to reach the dry trillion, but because of the various units of the private network is not fully interconnected, information resources to build and share relatively low, so that scientific research, academic resources in the digital after the full use of communication, "Information Island" problem has not been effectively resolved.

3, the service system computing capacity is uneven

Because each unit of data processing is completed locally, but the configuration of various servers does not necessarily meet the requirements, it caused the service system computing capacity imbalance. The service system with large data processing is prone to compute bottleneck, so it is necessary to upgrade the hardware equipment constantly in order to solve the problem of calculating bottleneck, which will generate new construction cost, while the service system hardware resources with smaller data processing amount are idle.

4. The issue of information security secrecy is becoming more and more prominent

Due to the lack of hardware construction funds caused by "one machine multiple use", not the scope of responsibility of the search, browsing, publishing and other acts, for information security confidential work brought new difficulties. The unit staff use the tile network to inquire the data, although enhances the work efficiency, sometimes can not correctly handle the information exchange between the Internet and the scientific research specialized network, thus causes the loss to divulge the incident.

The application model of cloud computing in the construction of scientific research informationization

Cloud computing (Cloud Computing) is grid computing (grids Computing), distributed Computing (distributed Computing), parallel computing (Parallel comput-in XOR), Utility computing (Utility Computing), networked storage (receptacle Storagetechnologies), Virtualization (virtualization), load Balancing (loading Balance) and other traditional computer technologies and network technology development and integration of products, is aimed at enterprises or institutions or individual users of the data processing capacity of the trend of increasing demand. At present, the definition of cloud computing in the academic community has not reached a consensus, but it is basically understood to use compute server clusters to build large-scale data centers, and through the _ Ear: networking or other large networks to provide computing resources to users on demand. The application of cloud computing includes the idea of consolidating the computing power of the server and redistributing it to users.

1, scientific research units to carry out the basic conditions of cloud computing

After years of information construction, our scientific research units have set up their own scientific research network and matching information center, accumulated rich experience in the construction and management of scientific research information. In some large scientific research units, on the one hand, due to the application of large demand, on the other hand has sufficient human and material resources, the size of its information center is basically reached the data centre level. In order to realize the effective sharing and full utilization of resources, the scientific research units should integrate the computing resources of the subordinate scientific research entities on the basis of the wide connection of the special network, and realize the cloud computing based on the information center, and build the cloud Computing data Center which integrates data resource storage, computing resource allocation and data security

2. The external network environment and internal architecture of cloud computing data center

The cloud Computing data center will be one of the base nodes of the research unit WAN.

Scientific research units will be subordinate research entities of the information Center unified integrated into the cloud computing data centers, the subordinate scientific research entities will no longer set two level information center, only a small number of storage servers.
