Survey of Desktop Virtualization in Higher Education: An Energy- and Cost-Savings Perspective

Benefits of utilizing desktop virtualization technology in higher education environments include the ability to deploy numerous applications, which may conflict on a traditional desktop, into a single image. Additionally, the utilization of thin-clients could produce substantial energy savings and reduce physical desktop replacement costs. Finally, virtualized desktops can be delivered to numerous non-enterprise devices, particularly student’s personal laptops or dorm-room computers. While there appear to be numerous benefits to desktop virtualization, there are many barriers to adoption. This paper outlines the substantial energy- and cost-savings provided through desktop virtualization in higher education. A literature review of relevant works and findings of a university implementation workgroup are presented using a case-study approach

Taxonomy of sustainable IT values

Sustainable IT is the effort towards design, manufacture, use and disposal of computer hardware efficiently and effectively with minimal or no impact to the environment. This implies biodegradability of defunct products and factory waste and energy efficiency. The performance of Green IT is a function of the `green\u27 steps taken towards sustainable IT. The development of green IT is a dynamic process and in the future may also have to address human health concerns. Several educational institutions of higher learning and technology companies have pioneered sustainable IT initiatives to achieve environmental and organizational sustainability. This study is a modest attempt towards classification of green IT initiatives and indicators, provision of taxonomy of sustainable IT values incorporated by businesses and educational institutions and analysis of their impacts on environmental, social and economic performance of organizations. The study examined the green IT initiatives undertaken by a sample of 20 Universities and 15 Corporates and identified the following sustainable IT values as responsible for sustainable IT: 1) Green Computing and Infrastructure Management, 2) Reducing carbon foot print, 3) Greening IT supply chain and sustainable software development, 4) Environment friendly electronic waste disposal, and 5) Institutions facilitating green IT and organizational sustainability. The study inter alia, recommends investment of 10% of corporate profits towards Sustainable IT Solutions; incentives for outstanding employees and their contributions towards green IT in firm\u27s promotion policy; creating awareness among employees regarding innovative sustainable practices as well as E-Governance to incorporate sustainable IT solutions

Mobile devices have become tremendously popular and they are an indispensable part of people’s everyday life, as well as a preferred option for accessing corporate IT infrastructure resources. Therefore, organisations need to design and implement efficient management solutions, based on in-depth analyses and in line with the specific properties of mobile devices. This research paper describes in detail corporate IT infrastructure and mobile devices as components of that infrastructure, reviews their use in business environment and presents appropriate tools for exercising control

Small cell cloud proof of concept implementation and monitoring schemes analysis

Cloud Computing has grown exponentially in popularity in the last few years, becoming a key technology for both personal and enterprise applications due to the numerous benefits it offers. On the other hand, Small Cell technology is considered by many to be the solution to the challenges that are expected to arise caused by the continuously increasing number of interconnected mobile devices. This project presents a basic design and a proof of concept implementation of a Small Cell Cloud, a current research field on mobile communications that aims to leverage the capabilities offered by the parallel and distributed computation of Cloud Computing to enhance Small Cells functionality. The purpose of the described Small Cell Cloud is to allow application offloading of mobile devices to Small Cells, allowing the execution of more resource demanding applications at the same time energy consumption is reduced in those devices. Furthermore, a detailed analysis on different Small Cell monitoring schemes is carried out, comparing the achieved performance with each of them in terms of data reliability and generated network traffic. Finally, based on the proof of concept implementation and a series of stress performance test, conclusions on the viability of the proposed Small Cell Cloud design and the most appropriate monitoring scheme are presented. Guidelines for future research work are also provided, considering the work developed in this project as a first step towards a new mobile technology.Ingeniería de Telecomunicació

Greening IT : How greener it can form a solid base for a low-carbon society

272 p.Libro ElectrónicoInformation Technology is responsible for approximately 2% of the world's emission of greenhouse gases. The IT sector itself contributes to these greenhouse gas emissions, through its massive consumption of energy - and therefore continuously exacerbates the problem. At the same time, however, the IT industry can provide the technological solutions we need to optimise resource use, save energy and reduce greenhouse gas emissions. We call this Greening IT. This book looks into the great potential of greening society with IT - i.e. the potential of IT in transforming our societies into Low-Carbon societies. The book is the result of an internationally collaborative effort by a number of opinion leaders in the field of Greening IT. Tomado de http://www.amazon.com/gp/product/8791936020The Greening of IT is a symptom of a much larger challenge for humankind - transitioning from economic childhood into maturity. Despite the emergence of large regional alliances such as the EC, humankind remains incredibly fragmented; and yet the need for global climate and energy policies is pressing. IT offers tantalizing technical solutions to our emissions and growth dilemma: it can grow greener and help with the greening of other industries. This book explores this potential.AcknowledgementsDisclosure1 Prologue2 Our Tools Will Not Save Us This Time - by Laurent Liscia3 Climate Change and the Low Carbon Society - by Irene N.

Assessing the evidential value of artefacts recovered from the cloud

Cloud computing offers users low-cost access to computing resources that are scalable and flexible. However, it is not without its challenges, especially in relation to security. Cloud resources can be leveraged for criminal activities and the architecture of the ecosystem makes digital investigation difficult in terms of evidence identification, acquisition and examination. However, these same resources can be leveraged for the purposes of digital forensics, providing facilities for evidence acquisition, analysis and storage. Alternatively, existing forensic capabilities can be used in the Cloud as a step towards achieving forensic readiness. Tools can be added to the Cloud which can recover artefacts of evidential value. This research investigates whether artefacts that have been recovered from the Xen Cloud Platform (XCP) using existing tools have evidential value. To determine this, it is broken into three distinct areas: adding existing tools to a Cloud ecosystem, recovering artefacts from that system using those tools and then determining the evidential value of the recovered artefacts. From these experiments, three key steps for adding existing tools to the Cloud were determined: the identification of the specific Cloud technology being used, identification of existing tools and the building of a testbed. Stemming from this, three key components of artefact recovery are identified: the user, the audit log and the Virtual Machine (VM), along with two methodologies for artefact recovery in XCP. In terms of evidential value, this research proposes a set of criteria for the evaluation of digital evidence, stating that it should be authentic, accurate, reliable and complete. In conclusion, this research demonstrates the use of these criteria in the context of digital investigations in the Cloud and how each is met. This research shows that it is possible to recover artefacts of evidential value from XCP

New work practices - "Desktop as a Service" and its adoption by the micro enterprise

THE PURPOSE OF THE STUDY The purpose of the study was to investigate the readiness of micro enterprises to adopt a new service under development by a Finnish telecommunication company. The new service called "WebTop" aimed at delivering computing resources to knowledge workers based on the Desktop as a Service model. In addition to assessing the overall demand for such a service, the research was designed to advise the development team on a set of features and applications to be included in the value proposition of the service. The final goal was to advise the development team about the viability of the service and find triggers that could promote its adoption by the desired target group. DATA The data used throughout this research was collected in 2008 through desk research and by interviews. The purpose of the desk research was to find existing DaaS providers, analyze their value propositions and revenue models. The primary data was collected by the means of face-to-face interviews with CEOs or owners of 31 Finnish micro enterprises. RESULTS The results indicate an overall lack of triggers of adopting DaaS as a new way of acquiring and using IT resources. The current IT needs of the micro enterprise are sufficiently satisfied by current practices. The finding indicate that the structure of decision making in the company and the need for customer relationship management tools and collaboration and communication tools are most likely to influence the adoption of cloud computing based services

Analysis of requirements and technologies to migrate software development to the PaaS model

Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Information Systems and Technologies ManagementSoftware development has been evolving during the last years and, more and more, the software architecture to support this development has become more complex to meet the new requirements and new technologies. With the new cloud computing architecture and models, IT departments and ISV are developing new applications and moving the traditional software architecture to the cloud. In this context, Platform as a Service (PaaS) model can provide software development services and components within a new architecture for building a new generation of software with all benefits of cloud, like scalability and elasticity. However, currently, most companies have significant challenges to adapt and change its software development process to use the PaaS architecture and the cloud services. In this dissertation, it will first be identified and analyzed the changes and challenges for develop software with the PaaS architecture. Afterwards, will be analyzed and identified the requirements in a traditional software development and architecture (on premise) to development new software or adapt the existents software with the PaaS.Dissertation submitted as partial requirement for obtaining the Master’s degree in Information Managemen
