SLA-aware dynamic resource provisioning for profit maximization in shared cloud data centers

Abstract

Dynamic resources provisioning is necessary for the multi-tier different virtualized application services in shared cloud data centers to meet different service quality targets. For an appropriate provisioning mechanism, we proposed a novel dynamic provisioning technique and employ a flexible hybrid queueing model to determine the virtualized resources to provision to each tier of the virtualized application services. We further developed meta-heuristic solutions, which is according to different performance requirements of clients from different levels. Simulation experiment results show that these proposed approaches can provide appropriate way to judiciously provision cloud data center resources, especially for improving the overall performance while effectively reducing the resource usage extra cost. So, it verifies the benefit of our methodology. © 2011 Springer-Verlag.
