基于SOA的计算系统可靠性优化方案

Optimum Proposal of Calculation System Reliability Based on SOA

针对传统的复杂计算系统面临的各种可靠性问题,总结了虚拟化技术在增强系统可靠性方面的优势,并将SOA体系结构的松散耦合、平台无关性等特点有机的结合,提出一种增强计算系统可靠性的系统架构——面向服务的虚拟化SOV(service oriented virtualization),对SOV系统在遭受可能的各种可靠性威胁分析归纳,然后运用虚拟化技术和体系结构的各种机制克服底层硬件故障、虚拟基础设施层运行错误、操作系统和应用服务程序运行错误、遭受攻击引起的故障等问题,综合增强系统的可靠性。

In order to solve the traditional problems on reliability of complex calculation, we summarize the superiority of Virtualization Technology , combine SOA＇ s loosecoupling, platform independent. We proposed a system architecture--SOV （service oriented virtualiza- tion）. We analyses the probable threats of SOV reliability, and then use virtualization and system structure mechanisms to overcome the bot tom hardware fault, the run error of virtual infrastructural layer, operating system and application service program, attacked faults and so on. Finally enhance the reliability of the system.
