Virtualization technology provides an opportunity to acieve efficient usage of computing resources. However, the management of services on virtualization infrastructure is still in the preliminary stage. Contstructing user service environments quickly and efficiently remains a challenge. This paper presents a service oriented multiple-VM deployment system (SO-MVDS) for creating and configuring virtual appliances running services on-demand. The system provides a template management model where all the virtual machines are created based on the templates with the software environment pre-prepared. To improve the deployment performance, we explore some strategies for incremental mechanisms and deployment.We also design a service deployment mechanism to dynamically and automatically deploy multiple services within virtual appliances. We evaluate both the deployment time and I/O performance using the proposed incremental mechanism. The experimental results show that the incremental mechanism outperforms the clone one.

Virtualization technology has provided an opportunity to the efficient usage of computing resources. However, the management of VMs on cluster is still in the preliminary stage. How to construct userpsilas task environments fastly and efficiently remains a significant challenge. This paper presents a multiple-VM deployment system (MVDS) for creating and configuring userspsila task environments on-demand. The system provides a template management model and all the VMs are created based on the templates including operating systems and applications. To improve the deployment performance, we explore some strategies about incremental mechanism and deployment tactics. We evaluate both the deployment time and I/O performance with proposed incremental mechanism. The experimental results show that the incremental mechanism outperforms the clone tactic.
