The MapReduce programming paradigm is gaining more and more popularity recently due to its merits of ease of programming, data distribution and fault tolerance. The low barrier of adoption of MapReduce makes it a promising framework for non-dedicated distributed computing environments. However, the variability of hosts resources and availability could substantially degrade the performance of MapReduce...
Check pointing is a widely used mechanism for supporting fault tolerance, but notorious in its high-cost disk access. The idea of memory-based check pointing has been extensively studied in research but made little success in practice due to its complexity and potential reliability concerns. In this study we present the design and implementation of REMEM, a Remote Memory check pointing system to extend...
Performance issues of multi-tier Web services have been studied extensively in recent years. Performance modeling and prediction under failure of multi-tier architectures, however, is not well addressed yet. We propose a novel model named Performance under failure of multi-tier architecture, or PerFAMA in short, to address this issue. We first show that the multi-tier architecture with failure considerations...
