A DBMS-based system for integrating grids and clouds: Anatomy, models, functionalities

This paper provides anatomy, models and functionalities of a DBMS-based systems for integrating Grids and Clouds. Our study starts from recognizing the similarity of some axioms of Grid and Cloud computing, still being these computational paradigms very different for what regards both computing and economic models. Our proposed system is centered along a well-designed DBMS schema that allows to obtain a seamless integration between Grids and IaaS Cloud providers. The paper details how images from a Cloud environment are deployed in reply to a specific task execution invoked from the (integrated) Grid environment, as well as other essential components of the proposed architecture (e.g., resource access and grant, user authorization, resource discovery and sharing, job and task management and distribution, integration with other computational platforms, and so forth).
