Research on Key Technology of Distributed Storage in Cloud Computing Environment

With the rapid development of network technology, cloud computing plays an important role in information technology. It is a new type of technology that improves efficiency and security in data processing. Distributed storage technology improves the efficiency of data storage and helps to improve the cloud computing. This paper analyzes the background of distributed storage technology under the cloud computing, discusses the composition of distributed storage technology, and introduces the practical application of distributed storage technology in cloud computing environment from different perspectives. Nowadays, the Internet has developed rapidly and plays a very important role in people's daily life, learning and work. With the development of network technology, the society is progressing, and the speed of information transmission is increasing. Cloud computing technology has emerged with the advent of a large amount of information, which has been widely applied in the information society. In different industries and fields, a large number of information should be calculated and stored. Therefore, in the link of cloud computing, the data center is the key. Now, based on the background of cloud computing, technicians should improve data analysis and control the unlimited data dynamically. Distributed storage technology is widely applied in people's life, reducing energy consumption and cost [1]. 1. The generation of distributed storage technology With the popularization of network technology, it is spread all over the people's work and life, and people have entered the era of Internet and large data. Information level is improving, massive information is surrounded by people every day, but the storage of information is restricted. Because storage medium has some limitations, it can not meet the needs of the masses. In view of this limitation, cloud computing has entered into people's life. Under the background of cloud computing, a large number of information resources can be reintegrated to achieve personalized mass demand. Cloud computing is generated on the basis of the development of the Internet. It is a common way of computing, expanding the way of resource sharing, and designing a computable computer model. The service provider is fully intelligent in the application, and does not need a lot of intervention, so the integration of all data can be perfected. In the links of accessing and storing network resources, a lot of information is integrated on the basis of network nodes, forming the way of network database, so that it can satisfy different users' needs. In the construction of infrastructure, all kinds of software and storage services are needed. The form of cloud computing is very large, and it has formed a large scale, but the cost of using it is very low. In the new computing model, cloud computing is fully applied to information resources with the help of data from different fields. The common service of hardware and software to cloud computing promotes the development of resources and makes the resources fully utilized and shared. In cloud computing, data center plays a very important role. Hardware is an important part. It has perfect storage capacity and reduces the 2018 4th World Conference on Control, Electronics and Computer Engineering (WCCECE 2018) Copyright © (2018) Francis Academic Press, UK 130 cost of data center. 2. Key technology of distributed storage in cloud computing environment In the high-speed development of Internet technology, the emergence of server equipment has a certain impact on traditional service mode, and the overall benefit of network technology is improved. The server based structure connects the servers through the network card through the connection of the network lines, so that they are in a whole network system, so as to realize the interconnection between servers. In this mode, using scientific data processing mode, we can find corresponding storage information, transmit packets timely, and achieve data sharing in a timely manner. This kind of structure and other structure comparison, the center server structure is relatively simple, without the aid of data transfer data in high speed forwarding equipment can make the whole structure and the circuit connection mode is more direct and simple, effective to prevent the problem of single tree structure. In the operation of the server, the transmission of mass information can be realized through the transmission of data information at the grass-roots level. But the server center structure will also have some problems, if there is compensation in the case of network operation, the load on the server running will be very large, cause the system equipment is not stable operation, also causes the operating costs increase, resulting in equipment overall effect can not fully play. Therefore, in the central structure of servers, the CAM CUBE structure is generally adopted, which realizes three dimensional nodes, and each node will connect to the server to form a three-dimensional network structure [2]. In the central structure, the switch is usually the central structure, and it is a kind of traditional type of distributed storage. With the continuous improvement of information construction, this kind of structure also presents a kind of limitations in the application, and can not achieve the diversification of the structure function. This kind of structure mainly uses switch as the main base point, and effectively connects the corresponding servers, but the server can only pray to store the effect of network information. This type of structure is centered on the switch and forms a tree structure, which is composed of the polymerization layer, the core layer and so on. The structure is not complex, and the way of connection is very simple. But nowadays, under the background of informatization, there are many data, huge data system, limited storage of information in tree structure, unable to effectively store massive information, and unable to satisfy all kinds of users' needs. Through the analysis of some aspects, the server as the center, the switch as the central structure, it has some limitations. The combination of the two can effectively make up for their shortcomings, and its scalability is effectively played, and routers and network structure are unified. In the network structure, servers and switches realize effective combination, make the function more diverse, better play the router's function, and the network structure is more flexible. In the process of cost construction, the cost of the operation of the equipment is effectively reduced. In extensibility research, this kind of hybrid structure has a certain relationship with the number of server network cards, and its space is limited. In specific aspects of the application, this kind of structure shows a mixed function, based on the high-speed transmission, information transmission in accordance with the order, in order to improve the efficiency and quality of data, make the transmission process more simple, to combine the superiority of various equipment reform. 3. Key technology of distributed storage in cloud computing environment In the traditional method of data storage, it is necessary to use efficient servers and specialized storage devices to improve the fault-tolerant effect of the technology. But in the specific technical analysis, the operation cost of the equipment will be very high, and the accuracy of the information data storage can not be improved effectively. In the link of cloud computing, it can effectively avoid the problem of data storage failure. In the related literature analysis, the node failure occurs during the operation of the system equipment. In the process of data collection, every 6 hours, there will be a node failure, which leads to the failure of data collection. The accuracy of data acquisition is not
