In this paper, we present and study a new system framework, which achieves allocation of cloud resource and guarantees response time of application requests and service rate of cloud resources. This architecture consists of three important components: queue controller, resource monitor and scale controller. The system leverages priority queue is used to assure response time of application requests. The resource monitor will measure the workload and resource status in cloud environment. In scale controller, an algorithm is proposed to guarantee service rate by adding/reducing cloud resources and address the tradeoffs between cost and service rate to avoid a waste of cloud resources. Finally, we evaluate this system framework through verifying feasibility and stability.
