Ontology Based Matchmaking System in Virtualization Enabled Resource Broker

6.1 GENERAL This chapter describes the limitations observed in conventional Grid architecture and the integration of virtualization techniques to address them. The integration of virtualization technologies in Grid infrastructure allows scheduling user's application to the potential physical resources even if they do not possess required application environment by creating virtual resources as 'leases' in them. In such cases, the matchmaking mechanism implemented in conventional Grid scheduler needs to be extended to determine potential resources to host virtual resources. To facilitate this, the Grid scheduler must be provided with information about capabilities of running virtual resources in it and the willingness of resource providers to support creation of resource leases. In this work, we propose an intelligent Grid resource brokering mechanism in which Grid resource information and other usage policies are represented using ontology. Such semantic representation can be exploited to make scheduling inferences using rule based reasoners. It helps the Grid scheduler in making a scheduling decision when potential resources need to be determined to create virtual resources in it for application execution.
