Virtualization enables the ability to consolidate multiple servers on a single physical machine, increasing the infrastructure utilization. Maximizing the ratio of server virtual machines (VMs) to physical machines, namely the consolidation ratio, becomes an important goal toward infrastructure cost saving in a cloud. However, the consolidation…

People live in an era of social, enterprise-oriented, and increasingly cloud-based technology; a dramatic shift away from stand-alone isolated silos that previously dominated. Computing systems can flourish today only when built to easily exchange data and services. An application that stands alone may provide practical functionality but may not…

Hiring substitute teachers used to be an early-morning calling burden for staff members at schools in Oregon's Coos Bay School District. Now that work has been passed off to Aesop, a service from Frontline Placement Technologies, which springs into action upon receiving a notification, either by call or log-in, from a teacher reporting an absence.…

This article discusses the research findings from the start-up phase of an innovative information and communication technology (ICT) project focused on ICT integration as a complex process involving many factors such as leadership, school readiness and organisational culture. Known locally as Hermes, the project's core objective was to provide an…

In these days of distance learners, virtual libraries, and electronic information, no library can be without some way of providing remote access to affiliated users, whether they are distance students, online students, or local students and faculty members working from home. Libraries subscribe to any number of electronic resources and journals,…

Universities can offer eLearning 2.0 tools and services to learners while obtaining clear benefits from releasing the control over some learning content. This means a shift from the institution centred and monolithic model of traditional virtual learning environments (VLEs) to a more heterogeneous and open model. This article tries to plot an…

It is proposed to establish an Integrated Distance Education System in India by designing modern technology based information communication network, connecting all its ODL (Open and Distance Learning) institutions to the headquarters of the ODL system in India. The principle roles to be performed by such a system have been discussed; according to…

Colleges and universities worldwide are turning to the hosted Software as a Service (SaaS) model and saying goodbye to issues like patch management and server optimization. Generally, SaaS involves applications (such as customer relationship management (CRM), enterprise resource planning (ERP), and e-mail) offered by a hosting provider. In this…

To date e-Learning material has usually been accessed and delivered through a central web server. As the number of users, the amount of information, the frequency of accesses and the volume of data increase, together with the introduction of multimedia streaming applications, a decentralized content distribution architecture is necessary. In this…

This paper examines the design and evaluation of a TV on Demand (TVoD) system, consisting of a globally accessible storage architecture where all TV content broadcast over a period of time is made available for streaming. The proposed architecture consists of idle Internet Service Provider (ISP) servers that can be rented and released dynamically…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
