A Novel Penalty Model for Managing and Applying Penalties in Cloud Computing

Managing and applying penalties has become a critical issue for Cloud Computing. In this paper we investigate this issue and present the most frequently used definitions of SLA penalty functions. We identify the characteristics of these functions highlighting their strengths and weaknesses. Then we propose a Novel Penalty Model for calculating the penalty cost of the violations, and present a formalization for this penalty definition. An example application will be presented to demonstrate the effectiveness of the proposed approach. Finally, the paper notes some challenges and future research directions.
