Client Virtualization Using VMware for Manageable Learning Environment at CSIBER

Every educational institution has a mandatory requirement of installing multiple operating systems and/or computing environments which is in line with the academic curriculum followed by the institution. Further, the fast growing and a dynamic IT trend demands constant upgradation and installation of new operating systems and supporting applications as the requirements change. To be competitive enough and to stay ahead in market place every educational institution tries its level best to tune itself as per various industry requirements. As such lab preparation is a constant ongoing process which poses a great burden on the shoulders of a system administrator involved in managing the learning environment in an educational institution. In order to support multiple operating systems on a single PC hard drive needs to be partitioned. At the same time this also poses greater inconvenience to students as they need to reboot the system every time they need to switch from one operating system to another. All these issues are addressed by VMware workstation software which enables to run multiple x86‐compatible desktop and server operating systems simultaneously on a single machine, in fully networked, portable virtual machines with no rebooting or hard drive partitioning required which proves to be an indispensible tool for every educational institution. In the current paper, the authors have proposed a model for the smooth functioning of a computer lab using VMware workstation software which dynamically gets tuned to the users requirements. The different levels of users are identified and tasks are assigned as per their role in the institution. Three-tier architecture is employed wherein different levels of users will be operating at different layers of the architecture. At the lowest layer VMware solution is proposed and only the admin has the privileges to interact with this layer. The model proves to be extensively user friendly for all levels of users.

Shadow IT를 고려한 새로운 관리체계 도입에 관한 연구

In a dynamic IT environment, employees often utilize external IT resources to work more efficiently and flexibly. However, the use of external IT resources beyond its control may cause difficulties in the company. This is known as "Shadow IT." In spite of efficiency gains or cost savings, Shadow IT presents problems for companies such as the outflow of enterprise data. To address these problems, appropriate measures are required to maintain a balance between flexibility and control. Therefore, in this study, we developed a new information security management system called AIIMS (Advanced IT service & Information security Management System) and the Shadow IT Evaluation Model. The proposed model reflects a Shadow IT's attributes such as innovativeness, effectiveness, and ripple effect. AIIMS consists of five fields: current analysis; Shadow IT management plans; management process; education and training; and internal audit. There are additional management items and sub-items within these five fields. Using AIIMS, we expect to not only mitigate the potential risks of Shadow IT but also create successful business outcomes. Now is the time to draw to the Light in the Shadow IT.

ON ENGLISH IT FIELD BORROWINGS IN MODERN RUSSIAN

Language is a reflection of society, which is developing with alterations in political, economic, and social spheres. As a result, some words lose their importance and fade into obscurity, whereas others come into existence. Despite the fact that the occurrence of borrowings is a global phenomenon, some spheres are more prone to accept foreign words, the dynamic IT field among them. As the USA have been leaders in the technical sphere for many years, the majority of the words describing IT concepts are of the American origin. Having entered the receiving language, some loan words may alter the meaning in order to avoid lexical competition and survive. To establish whether any semantic changes occurred, borrowings and their native counterparts have to be analyzed according to dictionary definitions as well as their contexts. Thus the aim of the present research was to analyze the issues of synonymy as well as the usage and meaning differences of English borrowings (nouns) of the IT field in the Russian language and their native counterparts. In order to perform the analysis, quantitative as well as qualitative research methods were applied. The quantitative method, particularly a corpus-based research, was employed while checking frequency and collecting the most frequent collocates of the loan words. The analysis of raw frequencies in the Russian National Corpus revealed that 21 loan words are widespread, whereas 25 of them are occasional. The majority of the loan words were found to be semantically narrowed. The analysis revealed that not a single one is in lexical competition with native Russian lexemes, since all of them are results of lexical addition rather than replacement.

The influence of IT and knowledge capabilities on the survival of university IT startups

Despite continuing interest in the role of university incubators in fostering IT entrepreneurship, empirical evidence on the link between incubation and IT startup survival has been mixed. This paper offers a fresh, unifying perspective by examining how university startups' IT-enabled agility relates to their survival. We use the resource-based view, dynamic capabilities and new product development (NPD) literatures to create a conceptual framework of the impact of startup firms' knowledge assets, technology capabilities, agility and innovation on their survival. Our framework suggests that startups' survival rates increase when they use dynamic IT knowledge capabilities to pursue innovations with emerging technology capabilities in rapidly evolving IT markets. Implications for university incubator research, policy and management are discussed.

MPI applications' performances in native vs. virtualized environments using InfiniBand IPoIB virtualization and live migration

Over recent years we have seen a constant evolution of High-Performance Computing moving into commodity servers cluster types of systems. At the same time we have seen Cloud Computing being a proven, stable and reliable IT paradigm, utilising virtualized clusters of commodity servers as key components. This paper presents a face-to-face native-to-virtual HPC MPI application performance analysis on a range of general-use HPC applications by virtualizing InfiniBand via IPoIB at the guest virtual machine level on VMware ESXi as well as KVM hypervisor with production ready live migration support. Applications running on various small and medium HPC clusters are targeted to address users, considering full IT infrastructure virtualization by merging general purpose with HPC IT infrastructure. Live migration is a key component within a virtualized environment as it enables dynamic virtual IT infrastructure, therefore live migration performance impact is evaluated through a pluggable multi-platform architecture on a proactive fault-tolerance use case.

Optimization of Edge Server Selection Technique using Local Server and System Manager in content delivery network

Cloud Computing is a distributing computing technology which is used as pay per use basis. Now a day’s Cloud Computing is the most reputed topic due to its ability to offer guaranteed quality of service atmosphere, dynamic IT infrastructures, and conFigureurable software services. But many users could not satisfy on cloud services completely due to their uncovering security purpose for handling large numbers of data. Even the network becomes uncontrollable, when large numbers of user’s request to the server create network congestion and data losses vigorously. Content Delivery Network OR CDN is an eminent solution of this problem. Our objective is to create local and global server and connect the global server to system manager, which is worked over Content Delivery Network to deliver and direct the user request to the nearest global edge server except local server and establish the connection between them and transfer the respective content. For optimization of edge selection process and reduce the load over content delivery network we approach local server concept in this paper.

Transformation and training for a mobile workforce: Sharing lessons learnt

The use of mobile technology has become more prevalent in the National Health Service as a sought after tool to improve quality and enable more efficient working. Across England, mobile working has been trialed with out of hours GPs, community nurses, midwives and emergency care providers. However, research has shown that many mobile working projects fail to fully realise the potential benefits or progress past pilot stage. This is often due to factors such as lack of appropriate strategy, business leadership or clinical engagement in the project. In December of 2013, Central London Community Healthcare (CLCH) Community Rehabilitation Services in Westminster and Kensington & Chelsea piloted a mobile working solution. The App provided the community clinicians with real time access to clinical data and the ability to document information at the point of care. CLCH promoted close collaboration between internal Information Management and Technology, the Transformation Team and frontline clinicians to overcome previously identified barriers. The project was unique, as it had to meet the user needs of multiple rehabilitation teams that work across different geographic areas. In addition, the teams were made up of multidisciplinary allied health professionals such as occupational therapists, physiotherapists and rehabilitation assistants. At times the project was challenged by issues of user skill, compliance, and technical support and was faced with a further complexity of high turnover of staff due to rotational programmes. The aim of this presentation is to share valuable lessons learnt in the form of ten top transformation tips. The presentation will provide practical, useful strategies for transformation projects utilising mobile working technology. The following strategies will be discussed: 1. Clinician centred transformation 2. Evaluate current work practice – ‘ As is’ process International Journal of Integrated Care – Volume 14, 01 November – URN:NBN:NL:UI:10-1-116522– http://www.ijic.org/ International Digital Health and Care Congress, The King’s Fund, London, September 10-12 2014. 3. Collaborate to develop new ‘To be’ working process 4. Analyse user digital and technological skills 5. Appoint mobile working champions 6. Timely distribute devices and kit to encourage self-directed learning 7. Multi-dimensional training 8. Dynamic IT support 9. Monitor and measure 10. Capture creativity and evolution The onset of the digital age with advances in care technology has provided great opportunities to improve the outcomes and experience for patients whilst making the jobs of clinicians easier. At CLCH, an innovative mobile working project identified that smart deployment, training and IT support to use new technology is essential in order fully achieve such benefits. At present there is a significant gap in documented guidance on how to actually carry this out. This presentation highlights some of the effective methods used by CLCH to embed a mobile working solution. We hope that this presentation will influence other services to explore, consolidate and share their core principles for successful digital and technology transformations.

Towards an Automated BPEL-based SaaS Provisioning Support for OpenStack IaaS

Software as a Service (SaaS) applications fully exploit the potential of elastic Cloud computing Infrastructure as a Service (IaaS) platforms by enabling new highly dynamic Cloud provisioning scenarios where application providers could decide to change the placement of IT service components at runtime, such as moving computational resources close to storage so to improve SaaS responsiveness. Moreover, emergent Internet of Things (IoT) scenarios enable novel computing applications involving several heterogeneous smart objects interacting with each other. These highly dynamic scenarios call for novel Cloud support infrastructures able to automate the whole SaaS provisioning cycle spanning from resource management to dynamic IT service components placement, including software deployment, components re-activation, and rebinding operations. However, notwithstanding the core importance of these functions to truly enable the deployment of complex SaaS over IaaS environments, at the current stage only partial and ad-hoc solutions are available. This paper presents a support infrastructure aimed to facilitate the composition of heterogeneous resources, such as single Virtual Machines (VMs), DB services and storage, and stand-alone services, by automating the provisioning of complex SaaS applications over the widely diffused real-world open-source OpenStack IaaS. Collected experimental results show the effectiveness of parallel execution of deployment steps introduced by our solution and demonstrate its applicability and advantages in a real SaaS production testbed.

Changing Use of Implantable Cardioverter Defibrillators (ICDs) in New Zealand from 2002 to 2012

Background: New Zealand Cardiovascular disease (CVD) risk guidelines advocate targeted risk assessment with the intensity of management determined primarily on the estimated five-year CVD risk. However, clinicians often find it challenging to explain to patients what the conceptofCVDriskmeansanduse this to supportpatients to change ‘risky’ lifestyles and behaviour. “Your Heart Forecast” is a relatively simple dynamic graphical IT application that conveys multiple CVD risk communication messages individualised for each patient in a coherent story. It provides a graphical story at the time of consultation of current risk (where you are now), how you compare to a peer with ideal risk factor control, what happens to your risk as you get older if you make no changes (the Forecast), and what would happen to your risk in future if you were able to make changes (e.g. stop smoking). Our aim was to evaluate whether the Heart Forecast tool facilitated risk communication compared with a standard risk assessment session using the NZGG colour chart display. Methods and results: One hundred current smokers (age 30–65) without prior CVDwere enrolled in Southland primary care. Theywere randomised 1:1 to anurse-led risk assessment session with or without use of the Heart Forecast tool. Each patient had pre-assessment questionnaire, risk assessment session and same-day reassessment. The questionnaires evaluated patient understanding of the determinants of risk, their understanding of their own absolute short and longer-term CVD risk, and motivation to make lifestyle changes. Enrolment has been completed and resultswill be available for presentation.

From dynamic capabilities to ERP enabled business improvements: The mediating effect of the implementation project

This study explores whether an Enterprise Resource Planning (ERP) implementation project mediates the relationship between dynamic pre-adoption capabilities and ERP-enabled business improvements. The results from our field survey of large ERP adopters in Austria suggest that the effects of the two out of three selected dynamic capabilities are dependent on the properties of the underlying organizational transformation project. While external information acquisition and IT governance capabilities are fully mediated by the performance of the ERP implementation project, decision making only directly impacts business capabilities. These results further our understanding about the role of the implementation project for ERP value creation and the different natures of capability relationships. We call for more research on co-presence conditions related to dynamic capabilities and IT transformation project performance.

Entrepreneurial firms and cluster competitiveness: institutions and public policy determinants

Globalisation brings many competitive challenges to emerging economies, particularly to small and medium-size firms (SMEs). Focusing on the information technology cluster in Brazil, Latin America’s largest economy, and a high-tech municipality (Campinas) the researchers examined the role of governmental institutions and their interaction with business and academe to foster competitiveness. Despite a high quality infrastructure and an excellent workforce, most public sector initiatives are not specific to SMEs nor to the needs of companies located in Campinas. Factors like: 1) the lack of a governance structure to coordinate policies in support of SMEs; 2) the absence of sufficient public resources to support innovation and bring new products to market; 3) the inaccessibility of research centres for small firms hinders the growth and development of Campinas as a dynamic IT cluster. The researchers propose 15 specific actions to improve the competitiveness of SME technology firms in Campinas and in the cluster.

Network Virtualization for QoS-Aware Resource Management in Cloud Data Centers: A Survey

The increasing popularity of Cloud Computing is leading to the emergence of large virtualized data centers hosting increasingly complex and dynamic IT systems and services. Over the past decade, the efficient sharing of computational resources through virtualization has been subject to intensive research, while network management in cloud data centers has received less attention. A variety of network-intensive applications require QoS (Quality-of-Service) provisioning, performance isolation and support for flexible and efficient migration of virtual machines. In this paper, we survey existing network virtualization approaches and evaluate the extent to which they can be used as a basis for realizing the mentioned requirements in a cloud data center. More specifically, we identify generic network virtualization techniques, characterize them according to their features related to QoS management and performance isolation, and show how they can be composed together and used as building blocks for complex network virtualization solutions. We then present an overview of selected representative cloud platforms and show how they leverage the generic techniques as a basis for network resource management. Finally, we outline open issues and research challenges in the area of performance modeling and proactive resource management of virtualized data center infrastructures.

Creating a global network of shared service centres for accounting

PurposeThe purpose of this paper is to contribute to the understanding of the practice of IT‐enabled management control change, in particular how IT‐driven change is made possible from a practical perspective in a global context. It does so by investigating the redesign of the telecommunications company Ericsson's global finance and accounting function from an independent structure of numerous national chief financial officer units into one interdependent global network of shared service centres.Design/methodology/approachEricsson's transformation was followed by drawing mainly on interviews and documents. The data were analysed using narrative and temporal bracketing strategies for theorising from process data.FindingsThe paper illustrates how IT‐enabled management control change unfolds as a continuous interaction between a dynamic organisational structure (social dimension) and a less, but still, dynamic IT (material dimension) across time. The study also highlights how such a process is metaphorically similar to the form of a hermeneutic spiral rather than the common perspective of an arrow from the present to the future.Research limitations/implicationsThe focus of the paper is on positive organisational change and how transformation is possible from a strategic and managerial point of view. Hence, less focus is placed on the employee perspective.Practical implicationsThis paper stresses the importance of pre‐understanding, an openness to trials and learning, and a dynami stance towards the moving targets of IT and organisation.Originality/valueThe paper provides rich empirical material. The analysis includes contemporary issues, and the practice of IT‐enabled management control change.

Thailand Moves to Connected Government

Thailand started its race for e-Government development with the policy frameworks of IT 2000 and 2010. The ICT policy frame works were then translated into the country’s ICT Master Plan to lay down e-Government architecture during 2002–2008. The IT2000 set target to lay basic foundation of ICT Infrastructure including human resource development. Whereby the IT2010 (2001–2010) which is set forward to achieve the ultimate goal of building up the country to the level of knowledge based economy and three specific goals are aimed: firstly to raise the technological capability of Thailand from “dynamic IT adopter” nation to “a potential leader”,secondly to increase the proportion of knowledge workers and thirdly to increase a contributable sum of knowledge-based industries to the country growth. To achieve these goals, IT2010 has identified five main flagships: e-Government, eEducation, e-Commerce, e-Society and e-Industry as the country’s e-development initiatives. Interpretation of the IT2010 has been depicted through the country’s first-ever ICT Master Plan (2002– 2006 and extended until 2008) with key objectives: to apply ICT to increase competitiveness, to develop a knowledge-based society, to apply ICT for sustainable development, and to develop business around the ICT industry. The second ICT master plan has currently been prepared and ready for deployment during the years 2009–2013. The succeeding master plan’s ambition is to further develop the country to a so called “Smart Thailand” where sustainable ICT implementation will be based on IT-literate-human capacity in all levels of society and on the good governance foundation in all development sectors as well as the accessibleto-all infrastructure. It is about time for reviewing the country’s ICT and e-Government direction and at the same time paving way for future fulfilling of substantial aims. Surveys, Interviews and studies on stakeholders including users, webmasters and government CIO community and the present environment conditions have been conducted by the Ministry of ICT to reflect facts and figures of the past e-Government services development as well as future development roadmap has been design as a step forward to leapfrog its maturity level of e-Government services development and to keep abreast with the international development arena.

The Effect of Information Technology on Arms‐Length Buyer‐Supplier Relationship

This paper posits that arm’s length buyer‐supplier relationship as the intermediate type between market exchange relations and strategic partnership might be advisable, and information technology may have a role as a mechanism actualizing the effects of such arm’s length relationship by strategic supply‐line diversification. Based on the theoretical analysis on interactive feedback relationships among IT level, buyer‐supplier relationships, and supply chain structure, we suggest a set of advisable buyer‐ supplier relationship type for efficient supply chain management. Also, doing so would be helpful in suggesting a dynamic IT investment and adoption model appropriate for the establishment of productive buyer‐supplier relationship, and further in providing theoretical foundations and practical guidelines on the role and function of B‐to‐B E‐commerce for efficient SC integration.

Comparison of the three CPU schedulers in Xen

The primary motivation for enterprises to adopt virtualization technologies is to create a more agile and dynamic IT infrastructure -- with server consolidation, high resource utilization, the ability to quickly add and adjust capacity on demand -- while lowering total cost of ownership and responding more effectively to changing business conditions. However, effective management of virtualized IT environments introduces new and unique requirements, such as dynamically resizing and migrating virtual machines (VMs) in response to changing application demands. Such capacity management methods should work in conjunction with the underlying resource management mechanisms. In general, resource multiplexing and scheduling among virtual machines is poorly understood. CPU scheduling for virtual machines, for instance, has largely been borrowed from the process scheduling research in operating systems. However, it is not clear whether a straight-forward port of process schedulers to VM schedulers would perform just as well. We use the open source Xen virtual machine monitor to perform a comparative evaluation of three different CPU schedulers for virtual machines. We analyze the impact of the choice of scheduler and its parameters on application performance, and discuss challenges in estimating the application resource requirements in virtualized environments.

Testing Event-Driven Business Processes

Today’s business climate requires to constantly evolve IT strategies for responding to new opportunities or threats. While the fundamentals of IT — reliability, availability, security and manageability — are still crucial, rapid results are mandatory for business success. These business challenges can be solved by acting with agility – striking the proper balance between the introduction of leading-edge technology and the pragmatic application of IT. In this paper, we introduce a testing framework for business solutions dealing with complex and dynamic IT environments. Our framework enables a test-driven development and adaptation of business processes in order to implement flexible and reliable business solutions. We compare our testing framework with model-driven development approaches and show how we applied it to an event-driven process management platform called SARI (Sense And Respond Infrastructure).
