Study of Several Fault Tolerance Methodologies in Distributed Environment
Lalit Gehlod · 2012
Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of (or one or more faults within) some of its components. If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naively designed system in which even a small failure can cause total breakdown. Fault tolerance is particularly sought after in high-availability or life-critical systems. This paper provides a learning of fault tolerance techniques in distributed systems, particularly replication and check-pointing. We have also suggested fault tolerance by replicated chechpointing in which both the tolerance techniques are combined. This work will help new scholars and students a good quality reference.
