Flexible fault tolerance in cloud through replicated cooperative resource group

摘要: Abstract Fault tolerance (FT) is a highly focused issue in cloud due to high reliability requirements especially for delay sensitive tasks. Numerous FT frameworks have been proposed literature. By and large, proactive reactive approaches are followed the existing frameworks. Irrespective of any applied approaches, implementation remains service provider centric Cloud users not given control over deciding level FT. However, follows orientation model with greater flexibility using computing services on demand basis pay-per-use manner. The user’s while executing their tasks will further reinforce cloud. Therefore, this paper proposes flexible fault framework (FFTF) FFTF provision categorize as premium/standard/economy implement corresponding (FT). To level, user task executed cooperative resource group Flexibility endorsed by maintaining performance parameters deadline guarantee ratio average different categories. analysed compared through extensive simulation experiments artificial real workload term its capability, consumption utilization an framework.
