Experiencing With the Cloud Over gLite

Executive Summary

Market competitiveness puts enormous pressures over companies to be agile in providing their offers and adapt to fast changes. In such context, resource dimensioning is a hard and risky task which may lead companies to under provision their data-center, and therefore be unable to cope with peak loads, or to overprovision it, and not fulfill their ROI. Cloud computing ought to provide such ability. In a previous work, the authors presented the solution for multi-tier web-based application hosting over a gLite based infrastructure. In this paper, they present a further development of the system towards the Cloud model. A scenario describing the system in action is also discussed.
