Dynamic Resource Allocation Algorithm for Virtualization Cloud Based on Quality of Service
Quality of service is an important indicator to measure the performance of dynamic allocation of cloud resources.This paper considers the four quality of service requirements of users'time,cost,security and reliability,and proposes a virtualized cloud resource dynamic allocation algorithm based on quality of service.The algorithm integrates ant colony algorithm and genetic al-gorithm.Firstly,genetic algorithm is used to generate effective initial pheromone for ant colony algorithm,four service quality indi-cators are used to define fitness function,and finally,ant colony algorithm is used to find the best resources.Experimental results show that the algorithm has good performance in terms of service quality assurance and resource balance.
