Distributed Application Checkpointing for Replicated State Machines

Application checkpointing is a widely used recovery mechanism that consists of saving an application's state periodically to be in case failure. In this study we investigate the utilisation distributed for replicated machines. Conventionally, machines, information stored way each replicas or separately single instance. Applying provides means adjust level fault tolerance approach by giving away from time. We use local cluster and cloud environment examine effects simple machine example compare results with conventional approaches. As expected, gains memory consumption utilise different levels while performing worse terms
