Towards a Resilient Hybrid IaaS Cloud with Ontology and Agents

The cloud computing paradigm with its pay-as-youuse business model is envisioned to provide immense benefits and promising returns. Hybrid cloud computing deployment model offers a viable solution of in-house private cloud with limited or unavailable resources on hand to meet the application requirements or at runtime. However, due to the large-scale, widely distributed and complexity of the underlying infrastructure, the cloud system is vulnerable to failures which are of great concern to users which may jeopardize the reliability and availability of cloud services. This paper describes our work-in-progress on using ontology and agents to provide support to achieve resiliency in hybrid cloud computing. Preliminary experimental evaluation provided promising results and insights on some important issues for future research directions.
