As clouds have been deployed widely in various fields, the reliability and availability of clouds become the major concern of cloud service providers and users. Thereby, fault tolerance in clouds receives a great deal of attention in both industry and academia, especially for real-time applications due to their safety critical nature. Large amounts of researches have been conducted to realize fault...
In the existing studies on fault-tolerant scheduling, the active replication schema makes use of ε + 1 replicas for each task to tolerate E failures. However, in this paper, we show that it does not always lead to a higher reliability with more replicas. Besides, the more replicas implies more resource consumption and higher economic cost. To address this problem, with the target to satisfy the user's...
Providing flexibility and extensibility, SIP has recently gained significant attention in many areas. Critical requirements on reliability, fault tolerance and security highlight the necessity of SIP robustness testing. There are only a few researches on SIP robustness testing. The biggest challenge is the anomalous message generation. This paper proposes a method and architecture for SIP robustness...
One of the major challenges in wide use of grid workflow systems is fault tolerance and avoidance. Checkpointing schemes provide a way of fault detection and recovery. In our research, we focus on performance optimization of checkpointing schemes for grid workflow systems. We propose a set of adaptive checkpointing schemes that dynamically adjust the checkpointing intervals online by using store-checkpoints...
Using store-checkpoints (SCPs) and compare-checkpoints (CCPs), we present an adaptive checkpointing scheme that dynamically adjusts the checkpointing interval on line in this paper. With additional SCPs and CCPs, we can use both the comparison and storage operations in an efficient way and improve the performance of checkpointing schemes. Further, we obtain methods to calculate the optimal numbers...
