Abstract—Web Cluster is able to combine a set of backend capacities to function as a powerful Web Server for handling massive workloads towards successful e-business. However traditional Web Cluster has shortcomings with pre-deployed and pre-configured capacities upon traditional rigid infrastructure, which will lead more cost into redundancy and wasteness because of inappropriate up-front capacity plan. Moreover the more energy will be consumed accordingly, as capacities were over-reserved for the rare peak. Thus a novel autonomic computing capacity management approach for overcoming such issues is therefore proposed in this paper. Firstly we present the novel approach with Cloud insight to provision virtual infrastructure for hosting Web Cluster instead of hosting Web Cluster upon a rigid infrastructure. Afterward we propose an autonomic provisioning mechanism based on Advance Reservation with Lend-Borrow policy and the low-high threshold detection algorithm, in order to enable capacity balancing and repurposing from Web Cluster adaptively with low demand to the other Web Clusters with high demand, so as to optimize the utilization of capacity efficiently on behalf of drawdown cost and energy saving. Finally we verify that, proposals in this paper are capable of provisioning elastic capacities in cost-effective and energy-saving way against capacity redundancy and wasteness, with a couple of simulations.
