Semantic distributed resource discovery for multiple resource providers

An emerging modus operandi among providers of cloud infrastructures is the one where they share and combine their heterogenous resources to offer end user services tailored to specific scientific and business needs. A challenge to overcome is the discovery of suitable resources among these multiple providers, which all have different resource management policies. We present a novel architecture for distributed resource discovery. Our solution provides inter- operability among heterogeneous resource provider, handles dynamic resources status updates, and supports infrastructure abstraction policies through the use of semantic web technol- ogy. We show the applicability of this architecture within the EU-FP7 research project NOVI.
