Abstract

Any mistaken maintenance for the complicated and distributed grid can bring unpredictable disaster. Here we focus on the system availability issues caused by service dependencies during the maintenance in grid. A novel mechanism, called Cobweb Guardian, 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, grid administrators can execute the maintaining task safely in runtime with high availability. The evaluation results show that our proposed dependency-aware maintenance can make the grid management more automatic and available.
