CLOUD COMPUTING SYSTEMS

A multi-tier cloud-metering framework for metering cloud resources is presented. The proposed framework is capable of relating metering indicator of distributed resources contributing to the same application and located at different architectural levels. Metering data is collected from the front-end, the cloud nodes and VMs, and propagated through the middle-tier of the metering architecture to be processed and stored at the back-end. The design of the metering framework adopts a service-oriented architecture which allow the processing of cloud metering objects CMOs using service processing over open web transport protocol. To be able to build the middle and back-end tier, a SOA based on IPIoE and BOSML is presented which allow full consolidation of cloud resources achieving scalability and reducing the amount of wasted resources due to cloud resources de-fragmentation.
