摘要
硬件冗余可以极大地提高计算机应用系统的可用性,然而,一旦关键硬件出现故障或数据库宕机,正在进行中的业务流程通常会中断。探讨了一种如何实现应用系统高可用性的软件架构的设计方案,以弥补纯硬件冗余应用系统的不足。
As everyone knows, hardware redundancy can greatly enhance the availability of computer application system. However, once key hardware or database fails, application service will be interrupted. This paper discusses a kind of high available software architecture to solve the problem of hardware redundancy.
