Abstract: This paper presents an ontology-based broker system for the interoperability of federated clouds. The system can provision cloud infrastructure resources from different platforms to meet the users' requirements of Infrastructure as a Service (IaaS). The system engaged an ontology to enable the interoperability of heterogeneous IaaS management platforms, OpenStack, Apache CloudStack and VMware ESXi. The system provisioned appropriate cloud-infrastructure resources from available platforms based on a vector-space algorithm. Evaluation results relying on the two data sets of non-scheduled and scheduled IaaS-user requests show that our system is practical in that average latencies to generate REST commands for virtual machine provisioning take less than a second per request and are linearly proportional to the number of provisioned servers.

Keywords: federated-cloud computing; cloud broker; cloud ontology; infrastructure as a service; interoperability.
