This paper aims to summarize the development trend of computer system infrastructure.In view of the current era Internet plus information system business scenarios,we analyze the mainstream method of computing resources allocation and load balancing.Meanwhile,to further improve transaction processing efficiency and meet the demand of service level agreement flexibility,we introduce a dynamic allocation method of computing resources for business objects.According to the reference value of the processing performance of the actual application system,the computing resources allocation plan and dynamic adjustment strategy ofeach business object were obtained.The experiment achieved the desired effect through large amount of data in the actual clearing business of the city card.%概述计算机系统基础架构的发展趋势.针对当前互联网+时代事务处理系统的业务场景,分析研究了计算资源分配与负载均衡的基本方法.为满足事务处理系统对业务对象的差异化服务需求,并充分发挥事务处理系统的整体处理能力,提出面向业务对象的计算资源动态分配方法.方法根据实际应用系统平台的处理性能基准值,确定各业务对象的计算资源分配计划及动态调整策略.通过城市一卡通实际清算业务大数据量的测试达到预期效果.
