In Cloud computing environment, there are various important issues, including information security, virtual computing resource management, routing, fault tolerance, and so on. Among these issues, the virtual computing resource management has emerged as one of the most important issues in past few years. As virtualization technologies become more prevalent, each Cloud user encounters the problem of building his/her own virtual cluster with less friendly interface of virtual resource management. To help resolving this issue, an on-demand virtual cluster in cloud web-based OS feature has been developed by the distributed computing Team in the National Center for High-performance Computing (NCHC). The on-demand virtual cluster system incorporates the autonomic computing and exhibits the ability to reconfigure itself to adapt to the changes in the Cloud environment.
