Study on fault tolerance method of cloud computing accounting service platform for middle data supporting cost-benefit analysis

Study the fault-tolerant method of intermediate data of cloud computing accounting service platform to support cost-benefit analysis, provide cost-benefit analysis function for the platform, and strengthen the fault-tolerant ability of intermediate data of the platform. Build an enterprise cloud computing accounting service platform, use the network environment of the accounting service platform provided by the cloud service provider, collect the internal and external accounting service system data of the enterprise through the data collection layer, and transmit it to the data warehouse of the data processing storage layer after data cleaning, extraction and processing. The data processing storage layer calls the collected data to analyze the transaction cost-effectiveness of the enterprise. The intermediate data fault-tolerant model is constructed. After being solved by ant colony algorithm, the intermediate data generated in the process of cost-benefit analysis and other accounting services are fault-tolerant processed, and the platform accounting service results are output to the interactive interface through the data output display layer, so as to realize the interaction with users. The experimental analysis shows that:this method can effectively analyze the transaction cost and benefit of enterprises, the data availability probability after fault-tolerant processing is higher, and the read-write load is lower.
