摘要： 面向服务架构(SOA)的业务负载震荡幅度较大，资源需求具有动态变化、按需索用的特点。为此，分析SOA与虚拟化的主要技术，在此基础上提出一种SOA资源保障模型，包括服务应用层、资源匹配层、逻辑虚拟层和物理资源层。实验结果表明，该模型较好地解决了用户级服务应用与底层物理资源的优化适配问题，并且能提高底层资源的利用率。

Abstract: The resource requirements under the Service-oriented Architecture(SOA) are characterized by dynamic variation and on-demand acquisition as a result of the high workload fluctuations. To solve the problem, this paper analyzes and discusses the major techniques of SOA and virtualization, then puts forward a resources guarantee model for SOA. It includes service application layer, resource matching layer, logic virtual layer and physical resource layer. Experimental result shows that the model can resolve the optimal adaptation problem between user-level application and bottom physical resources, and improve the utilization rate of bottom resources.

Key words: Service-oriented Architecture(SOA), virtualization, resource guarantee model, unified communication, dynamic allocation
