The Case Study of an F/OSS Virtualization Platform Deployment and Quantitative Results

In this paper we present practical experiences and results from the deployment of an F/OSS virtualization platform. EKT’s (NDC) core IT infrastructure was transformed to a virtualized one, using exclusively F/OSS, while severe budget and timing constraints were in place. This migration was initiated in order to better cope with EKT’s services requirements, while accommodating at the same time the need for the in house development of a large scale open access infrastructure. The benefits derived from this migration were not only generic virtualization benefits, such as the quantifiable reduced power consumption and cost reduction through consolidation, but also F/OSS virtualization specific ones.

Shared service components infrastructure for enriching the user experience in electronic publications

A major requirement for electronic publishing systems is the availability of rich and intuitive mechanisms that enhance the user experience of viewing and searching online electronic documents such as books, monographs and journal papers. This work concerns a set of infrastructural components and their utilization for the creation of related coherent services and features for end users. We present a set of sophisticated platforms, tools and mechanisms that have been employed in real-life cases for implementing document viewing and full-text search features, shared among application instances of various types. Challenges encountered and the provided solutions are discussed.
