Glossary

Index

Dynamic Provisioning for Community Services outlines a dynamic provisioning and maintenzince mechanism in a running distributed system， e.g. the grid，which can be used to maximize the utilization of computing resourccs and user clemands. The book indudes a complete and reliable-maintenance system solution for the large-scale distributed system and an interoperation mechanism for the grid middleware deployed in the United States， Furope and China. The experiments and evaluations have all been practically implemented for ChinaGrid，and the best practices establishee can help readers to construct reliable distributed systems.
　　This book is intended for researchers， developers， and graduate students in the fields of grid computing， service-oriented architecture and dynamic maintenance for large distributed systems.
