面向服务网格的虚拟环境部署运行管理系统

虚拟技术的最新进展为网格计算提供了封装资源的新方式，其封装性、隔离性和安全性能够有效屏蔽底层资源的异构性，根据用户应用需求定制执行环境，更好地适应于网格环境的复杂性和应用的多样性。为了满足当前服务网格的需求发展，基于新的虚拟机技术，研究适合于服务网格的虚拟环境部署运行管理系统，该系统为用户提供可视化、易操作的远程虚拟环境部署和运行管理功能；并实现一个标准的网格服务，结合服务网格平台CROWN，该服务可根据用户应用的特定需求动态透明地部署虚拟执行环境，并根据资源状态自适配调度执行用户任务。并对系统进行了实验分析，实验结果验证了系统的良好可用性和运行性能。

Virtual environment deployment and runtime management system for service grid

The latest development of virtual machine technology provides a new approach to integrate resources in grid environment.Its encapsulation,isolation and security can shield resource heterogeneousness,enable application specific execution environment,and provide better adaptability to the environment complexity and application diversity.To meet grid computing's current requirement,based on advanced virtualization technology,a service grid oriented system for virtual execution environment deployment and runtime management is proposed.A visible and easily manipulative approach is offered to deploy and manage a remote virtual environment,and a standard gird service is implemented so that virtual environments can be automatically deployed and managed according to application requirement,and user jobs can then be executed adaptively according to resource states.Having integrated with service grid platform CROWN,dynamic environment creation and job execution can be transparent to user.Analysis of experimental results show the feasibility and executing performance of this approach.
