Abstract

Cloud computing focuses on delivery of reliable, secure, sustainable, dynamic and scalable resources provisioning for hosting virtualized application services in shared cloud data centers. For an appropriate provisioning mechanism, we developed a novel cloud data center architecture based on virtualization mechanisms for multi-tier applications, so as to reduce provisioning overheads. Meanwhile, we proposed a novel dynamic provisioning technique and employed 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 users 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 and maximizing the global profit of cloud infrastructure providers. © 2011 IEEE.
