TopWith the increasing popularity of cloud computing, many researchers studied the performance of clouds for different types of applications.
Federated cloud concepts addressed in (Buyya, Garg & Calheiros, 2011) does not include customer-driven service management, computational risk management and autonomic management of Clouds which improve the system efficiency, minimization of SLA violation and the profitability of service providers.
The proposed models and techniques in (Buyya, Ranjan & Calheiros, 2010), are critical for the design of stochastic provisioning algorithms across large federated cloud systems where resource availability is uncertain. The mapping function (Wu & Buyya, 2010), is implemented by continuous double action, sensor unit was used to predict the geographic distribution of users. Federated cloud mechanism described in (Marosi, Kecskemeti, Kertesz & Kacsuk, 2011) does not deal the plan to investigate various scenarios that arise during handling federated cloud infrastructure using the FCM architecture.
SLA based Inter cloud operations in (Jrad, Tao & Streit, 2012) does not use simulation to investigate and evaluate the performance and efficiency of different SLA-aware match making algorithms by supporting multiple SLA parameters.
