@NewPaper: Engineering Cloud for QoS Assurance

Cloud computing is the latest computing paradigm that delivers IT resources as services in which users are free from the burden of worrying about the low-level implementation or system administration details. However, there are significant problems that exist with regard to efficient provisioning and delivery of applications using Cloud-based IT resources. These barriers concern various levels such as workload modeling, virtualization, performance modeling, deployment, and monitoring of applications on virtualized IT resources. If these problems can be solved, then applications can operate more efficiently, with reduced financial and environmental costs, reduced underutilization of resources, and better performance at times of peak load. In this paper, we present a provisioning technique that automatically adapts to workload changes related to applications for facilitating the adaptive management of system and offering endusers guaranteed Quality of Services (QoS) in large, autonomous, and highly dynamic environments. We model the behavior and performance of applications and Cloud-based IT resources to adaptively serve end-user requests. To improve the efficiency of the system, we use analytical performance (queueing network system model) and workload information to supply intelligent input about system requirements to an application provisioner with limited information about the physical infrastructure. Our Simulation-based experimental results using production workload models indicate that the proposed provisioning technique detects changes in workload intensity (arrival pattern, resource demands) that occur over time and allocates multiple virtualized IT resources accordingly to achieve application QoS targets.

Upcoming Book on Cloud Computing

Dr. Rajiv Ranjan — Wed, 27 Jul 2011 05:06:28 +0000

The goal of this handbook, titled “Cloud Computing: Methodology, System, and Applications”, is to give a comprehensive overview of the state-of-the-art of this emerging research area, which many believe to be the next platform for provisioning and delivering SaaS applications in various computing domains. The book also envisions future research topics and directions. This book is expected to serve as an important reference and a milestone for research on Cloud computing since 2007, when the term of “Cloud computing” was coined.

This book has been edited by Dr. Rajiv Ranjan along with collaborators from Indiana University, University of New South Wales, and Swinburne University of Technology.
