Executive Summary

A common perception of security services is an overhead on distributed system's performance that exponentially increases with scale and heterogeneity of the system's components. While this perception is not untrue, there is no precedence of experimenting the exact impact on its overall performance in terms of quality of protection. This paper presents a formal way of testing the impact of scalability and heterogeneity on the federated Cloud security services. The work presented in this paper aims to develop a mean of quantifying the impact on security functions under various operating conditions and parameters of federated Cloud deployments. The results of this experimental study will help businesses to identify the best security architecture that will fit their Cloud architectures and performance requirements.
