数据库云化部署技术研究

Research on Database Deployment Technology in Cloud Computing Environment

云计算虚拟化技术具备弹性可扩展、自动迁移(高可用)、自动恢复(高可靠)等特征,然而数据库系统自身技术的复杂性对在云计算环境中部署工作提出了调整。在研究与分析私有云汁算环境中数据库系统部署模式的基础上,在实际应用系统环境中重点验证了不同数据库系统采用单虚拟机部署模式时事务性能基准测试中的性能表现,通过与数据库在物理服务器部署方式下的性能对比,验证了数据库系统云化部署的可行性。

Cloud computing virtualization technology has the characteristics of elastic scalability, automatic migration （high availability）, automatic recovery （high stability）. Because of the natural complexity of database systems, it makes a big challenge to deploy database systems in cloud computing virtualization environment. On the basis of research and analyzing models of deploying database systems in private cloud environment, the TPC-C benchmark test with database instances running in cloud computing virtual machines was applied. Compared with performance results of same test with database instances running in physical machines, the feasibility of deploying database systems in cloud computing virtualization environment was verified.
