Construction of High-Availability Bank System in Virtualized Environments

摘要

With the development of mobile Internet and FinTech (Financial Technology), clients are raising their expectations for online banking systems. They now expect bank information system to provide sustained services with high quality and require the online banking system to manage various operational risks. Existing research on the construction of highly available systems mainly solves the problems how achieve High Availability of devices, system software, some particular systems, or how build an availability evaluation model. However, seldom schemes are designed to solve 2 problems: (1) the relationships between devices and businesses or between different businesses; (2) applications based on strong data consistency and integrity. This paper has a quick look at services, information system, and IT structure as well as data center infrastructure of the bank's online information system. Moreover, it proposes a scheme for highly available online banking system. We then designed a framework for the data center to reach High Availability under virtualized circumstances. Finally, both the experiment and industrial practices results show the effectiveness and efficiency of our proposed scheme.
