A Network Invoice Management Platform Based On Cloud Stack

In the invoice management of Hunan Local Tax Bureau,without timely and effective supervision,a large number of false invoices appear,threating to the tax collection order.In recent years,the high concurrent use of network invoice system,the different needs of different scale taxpayers and the hidden troubles of safety from the open Internet become the main problems of the network invoice management platform to solve.This paper mainly discusses the tax department network invoice application system based on cloud computing.Based on the open source CloudStack as the basic platform,combined with multi-tenancy technology,the system has the ability to deal with high concurrency,high safety and the application of customized effectively.The paper has mainly carried out the following work:(1)According to the characteristics of network invoice,the paper has analyzed and studied the cloud computing,virtualization and multi-tenancy,and then has discussed some key techniques and methods of CloudStack cloud platform based on network invoice.(2)The paper has planned and deployed the cloud management platform CloudStack and the server virtualization platform XenServer,then deeply analyzed the key software and hardware configuration.The realization of the system can provide computing power,network bandwidth and memory size according to the actual needs of users and can complete the automatic extension of load balance in accordance with the prescribed rules.(3)On the basis of the data centralization environment,the paper has completed the development of the network invoice application system with a detail list of the major functional modules and connections.(4)The paper has discussed how to meet the needs of tenants without increasing the complexity of the system,and how to give the customization based on MDA(Model Driven Architecture)of network invoice system for multiple tenants mode.(5)Combined with the tax characteristics of the industry,the paper has expounded andanalyzed the security of the network invoice in three areas: user login security authentication,the safety of the invoice data transfer and the safety generation of invoice anti-counterfeiting code and two-dimensional code.This paper comes to a conclusion: test results of the network invoice management platform have proved that it has still achieved high transaction throughput with the test environment equipment which is far less than the production performance of environmental equipment.
