Highly Available and Dependable E-learning Services Using Grid System

The development of the web based technologies had great impact on the E-learning systems. Developing pervasive, highly available and economical educational systems are so difficult or impossible in the client-server and web service architectures. The grid computing system can be used as a good platform for the low cost, online, highly available and mobile educational applications. The possibility of the failure/unavailability of resource in the grid during an e-learning service is not negligible and should be taken into consideration.
