摘要

在复杂的大规模分布式网格环境下

网格服务组件的维护是一个不容忽视的问题

不恰当的维护操作可能会带来不可预料的灾难.本文关注由服务间的依赖关系引起的网格维护期间系统可用性问题

提出了一种网格服务维护机制

针对网格服务组件提供了多种粒度(服务级

容器级和节点级)的维护.在使用了该机制后

网格管理员可以在运行时更安全地执行维护任务并保持较高的系统可用性.测试结果显示

我们提出的面向依赖关系的服务维护机制使得网格的管理变得更加自动和高效.

Abstract

Any mistaken maintenance for the complicated and distributed Grid can bring unpredictable disaster.Here we focus on the system availability problems caused by service dependencies during the maintenance in Grid.A novel mechanism is proposed in this paper.It provides multiple granularities (service-

container-

and node-level) maintenance for service components in Grid.By using the Cobweb Guardian

administrators of Grid can execute the maintaining task safely in runtime with high availability.The evaluating results show that our proposed dependency-aware maintenance can make the management for Grid more automatic and available.
