摘要
为了解决现有云计算平台的高度动态性和异构性带来的可靠性低的问题,提出了一种基于冗余调度的可靠云计算模型。针对云计算按需付费的特点,基于该可靠模型,建立了基于服务费用约束的冗余调度优化模型,以保证在该费用约束下获得最大的云计算服务可靠性。最后,用遗传算法解决该最优冗余分配问题。
In order to solve the problem of low reliability of Cloud Computing Platform for its own dynamic and heterogeneous,a reliable Cloud Computing model based on redundant scheduling is proposed.For the pay-as-need features of Cloud Computing,an optimal model redundant task scheduling for Cloud Computing based on the given cost of services is established to maximize the reliability of Cloud Computing.Finally,Genetic Algorithms is used to solve the problem of optimal redundancy allocation.
