QoS Metrics for Cloud Computing Services Evaluation

By Amid Khatibi Bardsiri Seyyed Mohsen Hashemi

DOI:, Pub. Date: 8 Nov. 2014

Cloud systems are transforming the Information Technology trade by facultative the companies to provide admission to their structure and also software products to the membership foundation. Because of the vast range within the delivered Cloud solutions, from the customer’s perspective of an aspect, it's emerged as troublesome to decide whose providers they need to utilize and then what's the thought of his or her option. Especially, employing suitable metrics is vital in assessing practices. Nevertheless, to the most popular of our knowledge, there's no methodical explanation relating to metrics for estimating Cloud products and services. QoS (Quality of Service) metrics playing an important role in selecting Cloud providers and also optimizing resource utilization efficiency. While many reports have got to devote to exploitation QoS metrics, relatively not much equipment supports the remark and investigation of QoS metrics of Cloud programs. To guarantee a specialized product is published, describing metrics for assessing the QoS might be an essential necessity. So, this text suggests various QoS metrics for service vendors, especially thinking about the consumer’s worry. This article provides the metrics list may stand to help the future study and also assessment within the field of Cloud service's evaluation.

Improvement of GVSRM with Addressing the Interoperability Issues in Global Village

By Mohammad Reza Mollahoseini Ardakani Seyyed Mohsen Hashemi

DOI:, Pub. Date: 8 Oct. 2014

In today's globally networked environment, enterprises need collaborating using Information Technology (IT) and other tools to succeed in this dynamic and heterogeneous business environment. The Global Village Services Reference Model (GVSRM) is a model based on SOSA (Service Oriented Strategies and Architectures) ontology for global village services realization. In this model, three architectural abstraction layers have been considered for global village: ‘infrastructure for global village services’, ‘global village services provisioning’, and ‘using global village services’. Despite of relative completeness of this model, one of its obvious shortcomings is lack of attention to the crucial issue of interoperability in the global village. Based on this model, the grid of global village is comprised of VHGs (Virtual Holding Governance). The VHG is a temporary, scalable, dynamic cluster/association comprising of existing or newly service provider organizations which its aim is satisfying the requirements of global village actors through electronic processes. In this paper, we will propose a federated approach for interoperability among the VHGs of the global village and then improve the GVSRM by adding the corresponding interoperability components to it.
