QoS Guaranteed and Cost-Efficient Resource Management of PaaS based on IaaS
As one of the three service models of cloud computing,PaaS (Platform as a Service) has gained more and more popularity for its capabilities in optimizing development productivity and business agility.However,the traditional PaaS uses the dedicated infrastructure,which might lead to low infrastructure utilization rate.To solve the above problem,PaaS based on IaaS (PoI) emerged,in which IaaS (Infrastructure as a Service) is involved to optimize the utilization of the infrastructure.Because PoI has many characteristics,resource management mechanisms used in the traditional PaaS or IaaS could no longer adopted in PoI.In this paper,an adaptive resource management framework and the corresponding scaleup,scale-down algorithms are brought forward to guarantee the QoS of applications deployed in PaaS platform as well as decrease the rental cost of VMs from IaaS providers.Experimental results show that the resource management mechanisms proposed in this paper can not only guarantee QoS of all applications,but also improve the utilization rate of the infrastructure,thus to make PoI possess the advantages of both PaaS and IaaS.
