Abstract:

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.

Key words: cloud computing, virtual machine, database, performance
