Big data and cloud computing related technologies are developed in concert to perform data analysis and provide data references for economic management. Cloud computing is a computing model that provides services through the Internet. Cloud computing is based on the Internet and virtual technologies. It provides users with virtualized resources and data. Depending on the resources provided by the cloud, it can be divided into IaaS, SaaS, PaaS and IIaaS. Users access and use cloud resources through the Internet, and only need to pay for the use of cloud resources. For the construction and maintenance of cloud resources, the internal deployment and structure of cloud resources need not be concerned. Utilize cloud computing and use distributed computing to obtain storage and computing capabilities, replacing local computers or remote servers. Cloud computing integrates server clusters, highly reliable IDCs, and various applications. The system implements automated management to provide IT services to customers. The main characteristics of cloud computing include the following aspects: cloud computing has a resource sharing pool, the information system integrates, classifies, and outputs various resources, and outputs related information according to different instructions; Cloud computing performs selfdata calculation without human operation; cloud computing outputs services to the outside in a unified manner, and users access the cloud as needed, and are divided into application services, infrastructure services, and platform services according to the required service level; The computing access function is extensive, allowing multiple terminals to access through standard mechanisms.

Financial management model based on cloud computing in the context of big data
In the context of big data, cloud computing technology realizes resource sharing through the Internet and virtual technologies. Centralizing all resources in the cloud storage center can provide powerful data processing and data storage services for enterprise users. Enterprise users only need to use simple terminal devices, purchase the service, and enjoy the storage resources and data processing functions provided by cloud computing services through the Internet. The enterprise's data information center will run on the Internet. Enterprise applications can flexibly switch computer resources according to different business access requirements and flexibly configure the enterprise. Information processing capabilities, greatly reducing information processing costs.

Construction of financial computing service center based on cloud computing
Internet technology is widely used in enterprises, and networking provides a technical foundation for companies to collect various types of big data. Based on the maturity of big data analysis technology, research and build and develop cloud computing financial shared service center services.

Finance cloud management structure
Finance cloud is the application of cloud computing technology in the financial sharing service center. In cloud computing, the client and the cloud are two important modules. The client is the port through which the user accesses and obtains information, providing users with accurate information. In the cloud, the structural layer is composed of four layers. The application layer continuously improves services such as guarantee management and fund management. The data management layer provides information support. The network service layer uses network storage, email, and web addresses to improve basic network services. The detailed structure diagram of Finance Cloud is as follows:

Model and Construction Strategy of Financial Shared Service Center Based on Cloud Computing
English units may be used as secondary units (in parentheses). The financial shared service center involves many departments and staffs, and to deal with many matters, it is necessary to make a design plan for the construction model in advance and formulate a construction strategy suitable for its own characteristics. The cloud computing-based financial shared service center construction model roughly includes processes, organization and human resources, information systems, and operations management. Build strategy. The process of developing normative standards, including activities such as receiving input and generating output. Process design and reengineering include scheme planning and design, test improvement and process optimization; According to different strategic goals of cloud computing financial shared services, rationally arrange and organize organizational structure and staffing, and establish a performance evaluation system; Build an information system; build an integrated operation and management system based on the value chain.
