Optimally organizing distributed-component computing in the clouds: From both the user perspective and resource view

With the sharp increase of computing demands, computations more and more rely on the distributed components. However, the relatively inferior quality of wide-area networks hampers such trend. This paper proposes an approach aiming at optimally organizing the distributed-component computing in the current Internet in which some nodes with large computational freedom and capability for the public to compute are emerging, such as the initially born data centers in the present Cloud computing environments. Both the user experience and the resource utilization are taken into the quantitative analysis and optimization. Facing the exponential growth of the problem´s solution space, this paper develops an effective approach. Experimental simulations show that the approach generates the result significantly approximating the optimal solution, in the meantime with high efficiency.
