Abstract

Virtualization is the simulation or emulation of computer resources to the user (Grauer, n.d.; Simpson, 2008). This chapter discusses virtualization as a viable classroom methodology for providing students with course relevant hands-on experience (Simpson, 2008) while synchronizing course specific content in traditional on-ground and online courses (Pheils, 2010). More specifically, this chapter provides an overview of virtualization, detailing several open source tools, and offering possible applications for incorporation into other courses including free resources for sample content. Proof-of-concept is established through examples of successful usage at two colleges. The adoption of virtualization within course development may provide a solution that spans disciplines and offers students the ability to practice and further their studies beyond the classroom.

Abstract

Purpose

The purpose of this study is to investigate whether online apparel shoppers' adoption of product virtualization technologies is facilitated more by hedonic motivations than functional motivations due to the hedonic nature of the product virtualization technologies.

Design/methodology/approach

In addition to the focus group interview, two separate online surveys with links to a stimulus web site containing one of the two product virtualization technologies was conducted to a national online shopper sample. The data were analyzed using structural equation modeling by comparing the structural coefficients of hedonic and functional motivations on the attitude toward using the product virtualization technologies. The linear combination of functional and hedonic roles of each technology was examined using discriminant function analysis to see if the results were consistent.

Findings

The results showed that the hedonic motivation had a stronger positive relationship than functional motivations with the attitude toward using product virtualization technologies. The empirical findings of this study confirm our proposition that perceived entertainment value is a stronger determinant of attitude toward using product virtualization technologies than perceived usefulness.

Originality/value

The findings of the paper support the idea that the direction of technology acceptance model related research should be drawn by the (functional or hedonic) purpose of the technology/system. Based on the current findings, it seems likely that the predictive importance of the hedonic or functional benefits on attitude toward using a particular technology/system will depend, to a large extent, on the primary purpose of the system/technology.

Abstract

Purpose

The purpose of this paper is to understand how higher education institutions (HEIs) in developing countries can migrate their physical administrative work environment to a virtual platform to improve information management.

Design/methodology/approach

The paper employs an interpretive case study approach and a combined lens of activity and agency theories to understand how a developing country HEI attempted to improve its information management by migrating from a physical to a virtual administrative work environment.

Findings

The findings show how contradictions caused by role conflicts, administrative staff’s fear of elimination and external consultants’ limited understanding of administrative rules and procedures can hamper work environment virtualisation. Such challenges should be resolved in order to achieve a successful virtual work environment that supports timely and accurate information management.

Research limitations/implications

The study is limited by its single case perspective in one developing country. However, future studies can compare the experiences of HEIs from developed and developing countries in order to account for contextual differences.

Practical implications

The study provides practitioners with insight into how to address conflicts between employees (as potential users) and external consultants during virtual system development and implementation. In particular, role conflict, fear of eliminating some administrative staff and consultants’ limited understanding of administrative work procedures should be resolved for successful work environment virtualisation.

Originality/value

The study is the first attempt to offer rich insight into the challenges associated with administrative work environment virtualisation for improved information management in HEIs, through the principal-agent relationship.

Abstract

The recent rapid commercialization and adoption of Internet technologies has driven a process of supply chain virtualization, transforming conventional work practices across organizations. In an effort to provide a better understanding of this emerging phenomenon, this paper presents three key elements of supply chain virtualization, including: the formation of virtual trading communities; the emergence of virtual knowledge communities; and the relocation and integration of inter‐organizational business processes in the cyberspace. The transformations and consequences of virtualization are illustrated in the context of the Hong Kong textile and clothing industry. The experience of Hong Kong suggests that supply chain virtualization has propelled a structural change in buyers‐intermediaries‐sellers relationships, called for a novel approach to knowledge management, and accelerated internationalization of small‐ and medium‐sized enterprises. Managers and policy makers are advised to adopt new mindsets and practices in the face of these challenges.

Abstract

Purpose

The physical server transition to virtualized infrastructure server have encountered crucial problems such as server consolidation, virtual machine (VM) performance, workload density, total cost of ownership (TCO), and return on investments (ROIs). In order to solve the problems mentioned above, the purpose of this paper is to perform the analysis of virtualized cloud server together with shared storage as well as the estimation of consolidation ratio and TCO/ROI in server virtualization.

Design/methodology/approach

This paper introduces five distinct virtualized cloud computing servers (VCCSs), and provides the appropriate assessment to five well-known hypervisors built in VCCSs. The methodology the authors proposed in this paper will gives people an insight into the problem of physical server transition to virtualized infrastructure server.

Findings

As a matter of fact, VM performance seems almost to achieve the same level, but the estimation of VM density and TCO/ROI are totally different among hypervisors. As a result, the authors have the recommendation to choose the hypervisor ESX server if you need a scheme with higher ROI and lower TCO. Alternatively, Proxmox VE would be the second choice if you like to save the initial investment at first and own a pretty well management interface at console.

Research limitations/implications

In the performance analysis, instead of ESX 5.0, the authors adopted ESXi 5.0 that is free software, its function is limited, and does not have the full functionality of ESX server, such as: distributed resource scheduling, high availability, consolidated backup, fault tolerance, and disaster recovery. Moreover, this paper do not discuss the security problem on VCCS which is related to access control and cryptograph in VMs to be explored in the further work.

Practical implications

In the process of virtualizing the network, ESX/ESXi has restrictions on the brand of the physical network card, only certain network cards can be detected by the VM. For instance: Intel and Broadcom network cards. The newer versions of ESXi 5.0.0 and above now support parts of Realtek series (Realtek 8186, Realtek 8169, and Realtek 8111E).

Originality/value

How to precisely assess the hypervisor for server/desktop virtualization is also of hard question needed to deal with it crisply before deploying new IT with VCCS on site. The authors have utilized the VMware calculator and developed an approach to server/desktop consolidation, virtualization performance, VM density, TCO, and ROIs. As a result, in this paper the authors conducted a comprehensive approach to analyze five well-known hypervisors and will give the recommendation for IT manager to choose a right solution for server virtualization.

Abstract

Purpose

Social enterprises (SEs) have emerged as a tool to sustainable development. SEs create a social value along with an economic value. However, the aspect of SEs still missing from literature is the process of virtualization. The purpose of this paper is to introduce international social entrepreneurship as an emerging form of social entrepreneurship that is using information and communication technology (ICT)-enabled innovation and networking with international partners as virtual enterprise network, to create social and economic values across the borders.

Design/methodology/approach

In this paper, qualitative research paradigm is adopted to study the internationalization of SEs. To identify the drivers of internationalization, in-depth literature review was conducted. Articles from six databases and Google Scholar were searched to propose a comprehensive model for internationalization of SEs.

Findings

There is limited academic work on the use and impact of digital intervention (ICTs) on SEs and, especially, on the virtualization of SEs as there is no paper explaining virtualization of SEs. This paper proposes a model for the internationalization of SEs, named virtual social enterprise.

Research limitations/implications

The conceptual models and discussions on the virtualization of SEs are very limited in the extant literature. Very few articles could be found that studied the process of internationalization of SEs. Thus, the paper would have far-reaching implications for social enterprise theory and practice.

Originality/value

This is first study of its kind proposing a comprehensive theoretical model for internationalization of SEs. This model could be used by SEs for networking across international boundaries to control the flow of information and to market their products.

Abstract

Purpose

The purpose of this paper is to describe a virtualisation model of RFID enabled infrastructure incorporating non‐standard radio frequency identification (RFID) components. The model is implemented as a software service that draws upon other sources of internet services.

Design/methodology/approach

In a global supply chain environment, circumstances at different locations may not allow RFID system to be used. Some supply chain members do not have compatible network infrastructure in place. These include RFID frameworks such as China's National Product Codes and Japan's ubiquitous identification which are utilised around the world. There is also a reachability problem for consignments going offsite. The paper introduces a service abstraction layer (SAL) in the RFID architecture to remove dependency on specific RFID framework. From this principle, the paper introduces a new virtual infrastructure that interfaces with emerging identification technologies.

Findings

The model bridges the gaps that exist between various RFID standards, as well as utilising various technologies to emulate data capture devices so that the information chain remains intact across the global network. The resulting system significantly reduces the costs of commissioning and operating costs of existing RFID infrastructures.

Research limitations/implications

The new system has been tested in real industry environment with defined scope and coverage. The implication due to full roll out of the technologies in global supply chains still requires further investigation.

Practical implications

Usability of the virtualised RFID infrastructures depends on the cooperation among partners in the supply chain rather than the technology level. New business rules are required when special stakeholders such as customs are included in this virtualised infrastructure.

Originality/value

The concept of virtualisation has been used in operating systems, but its application to supply chain has not been explored before. Introduction of the SAL allows interoperability of systems handling goods tracking events through the supply chain.

Abstract

Purpose

The purpose of this paper is to consider how and why virtual machines (VMs) and cloud computing and related development environments built on cloud-based resources may be used to support and enhance the technological elements of library and information science (LIS) education.

Design/methodology/approach

It is based on analysis of available technologies and relevant applications.

Findings

Cloud computing and virtualization offer a basis for creating a robust computing infrastructure for LIS education.

Practical implications

In the context of LIS education, cloud computing is relevant in two respects. First, many important library and archival services already rely heavily on cloud-based infrastructures, and in the near future, cloud computing is likely to define a much larger part of the computing environment on which libraries and archives rely. Second, cloud computing affords a highly flexible and efficient environment that is ideal for learning about VMs, operating systems and a wide variety of applications. What is more important, it constitutes an environment for teaching and learning that is vastly superior to the ones that currently support most LIS degree programs. From a pedagogical perspective, the key aspect of teaching and learning in the cloud environment is the VM. So, the article focuses a significant portion of its attentions on questions related to the deployment and use of VMs and Linux Containers, within and without cloud-based infrastructures, as means of learning about computer systems, applications and networking and achieving an understanding of essential aspects of both cloud computing and VM environments.

Originality/value

Based on a search of available literature in computer science and library and information science, the paper has no counterparts.

Abstract

Purpose

In this paper, a three-dimensional (3D) printer-based manufacturing line and supporting system, which supports personalized/customized manufacturing for individual businesses or start-up companies, was studied to evaluate the practicality of using additive manufacturing for personalization/mass customization.

Design/methodology/approach

First, factory-as-a-service (FaaS) system, which provides factory as a service to customers, was proposed and designed to manufacture various products within a distributed manufacturing environment. This system includes 3D printer-based material extrusion processes, vapor machine/computer numerical control machines as post-processes and assembly and inspection processes with an automated material handling robot in the factory. Second, a virtualization module for the FaaS factory was developed using a simulation model interfaced with a cloud-based order and production-planning system and an internet-of-things-based control and monitoring system. This is part of the system for manufacturing operations, which is capable of dynamic scheduling in a distributed manufacturing environment. In addition, simulation-based virtual production was conducted to verify and evaluate the FaaS factory for the target production scenario. Main information of the simulation also has been identified and included in the virtualization module. Finally, the established system was applied in a sample production scenario to evaluate its practicality and efficiency.

Findings

Additive manufacturing is a reliable, feasible and applicable technology, and it can be a core element in smart manufacturing and the realization of personalization/mass customization.

Originality/value

Various studies on additive manufacturing have been conducted with regard to replacing the existing manufacturing methods or integrating with them, but these studies mostly focused on materials or types of additive manufacturing, with few advanced or applied studies on the establishment of a new manufacturing environment for personalization/mass customization.
