Resource optimization with reliability consideration in cloud computing

A new comprehensive optimization model based on queueing theory is proposed for resource allocation in cloud computing. Response time reliability is considered in our proposed model, which is proved to be essential through our case study. Using our optimization model, the optimal resource allocation of cloud computing strategy is achieved by minimizing the energy with the constraints of average response time, response time reliability, stable of the queueing system and the maximum allowable quantity of the resources. Our case study shows that considering response time reliability is very important to ensure the service quality in cloud computing resource allocation.
