FLEXIBLE ROLLBACK RECOVERY IN DYNAMIC HETEROGENEOUS GRID COMPUTING
INTRODUCTION
Grid Computing
• Virtual computer architecture over distributed process execution.
Computational Grid
- Infrastructure.
- Standard Protocols.
Data Grid
- Share and Manage distributed data.
- Access database.
- High speed data movement.
• Fault Tolerant Grid Computing
• Complexity of infrastructure needs
- Reliability
• The absence of Fault Tolerance mechanisms.
• Need for Rollback Recovery.
EXISTING SYSTEM
• Communication Induced Check-pointing protocols.
• Pro-Active system using Asynchronous Sequential Processes
DISADVANTAGES
Lack of Heterogeneity and Dynamic nature.
Probability of failures and crashes are more.
Reliability decreases and Mean Time to Failures decreases
Efficient Theft detection
Rollback recovery
Reliability
Mean Time to Failure (MTTF)
