Abstract:

With help of a new cost-aware cloud service request scheduling algorithm based on dynamic reuse, according to current system load and divisible character of cloud service requests, the virtual resources can be rent and reused on demand to achieve optimal scheduling of dynamic requests in reasonable time.The rental cost of the overall infrastructure for increasing cloud service providers’ profits can be minimized when meeting service level agreement constraints. Simulation indicates that our proposed algorithm shows better performance compared with other revenue-aware algorithms in terms of resource utilization and operation profit.

Key words: cloud service, service level agreement, cost-aware, virtual machine, generic algorithm
