With the ever-growing use of cloud computing by practitioners and also the emphasis placed by researchers from various backgrounds on this field, collaboration between various clouds has emerged as a new research area garnering a lot of attention in recent years. Cloud Federation, in which different clouds interact for purposes such as increased productivity and decreased costs, is one aspect of this new trend, which although faced with many challenges,has the potential to make cloud computing even more pervasive then before.In this thesis, by focusing on statistical multiplexing in the resource usage behavior of cloud requests, we evaluate the efficient and fair partitioning of requests in...
