Smart cloud federation simulations with CloudSim

In the last few years the broad diffusion of Cloud Computing has encouraged the proliferation of cloud computing providers. However, providers often propose their services using proprietary management software, interfaces and virtualization technologies. This strongly hinders the applications interoperability and migration across providers boundaries. Organizing providers in federations seems promising for addressing such issues, but it introduces other challenges to be faced, often requiring innovative approaches. Unfortunately, the evaluation of new solutions in a repeatable manner and under several configurations is a hard task to achieve using real Clouds platforms. For these reasons we propose SmartFed, a simulator for cloud federations that is able to model the richness typical of an environment with multiple cloud providers. We show the capability of SmartFed by simulating a sample mapping process for assigning applications to providers.
