By George Kousiouris,Andreas Menychtas,Dimosthenis Kyriazis,Kleopatra Konstanteli,Spyridon V. Gogouvitis,Gregory Katsaros,Theodora A. Varvarigou
Issue Date:October 2013
In modern utility computing infrastructures, like grids and clouds, one of the significant actions of a service provider is to predict the resources needed by the services included in its platform in an automated fashion for service provisioning optimizati...
Migrating Legacy Software to the Cloud with ARTIST
2013 17th European Conference on Software Maintenance and Reengineering (CSMR)
By Alexander Bergmayr,Hugo Bruneliere,Javier Luis Canovas Izquierdo,Jesus Gorronogoitia,George Kousiouris,Dimosthenis Kyriazis,Philip Langer,Andreas Menychtas,Leire Orue-Echevarria,Clara Pezuela,Manuel Wimmer
Issue Date:March 2013
As cloud computing allows improving the quality of software and aims at reducing costs of operating software, more and more software is delivered as a service. However, moving from a software as a product strategy to delivering software as a service hosted...
Interactive Social TV on Service Oriented Environments: Challenges and Enablers
Games and Virtual Worlds for Serious Applications, Conference in
By Dimosthenis Kyriazis, George Kousiouris, Andreas Menychtas, Anastasios Doulamis, Theodora Varvarigou
Issue Date:May 2011
Future Internet Applications require the on-demand provision of ICT assets with regard to data, services and process technologies. What is missing from today's service platforms to realize this vision refers to the way services are perceived to work and as...
A Service-Oriented Framework for GNU Octave-Based Performance Prediction
Services Computing, IEEE International Conference on
By George Kousiouris, Dimosthenis Kyriazis, Kleopatra Konstanteli, Spyridon Gogouvitis, Gregory Katsaros, Theodora Varvarigou
Issue Date:July 2010
Cloud/Grid environments are characterized by a diverse set of technologies used for communication, execution and management. Service Providers, in this context, need to be equipped with an automated process in order to optimize service provisioning through...
Platform-as-a-Service Architecture for Real-Time Quality of Service Management in Clouds
Internet and Web Applications and Services, International Conference on
By Michael Boniface, Bassem Nasser, Juri Papay, Stephen C. Phillips, Arturo Servin, Xiaoyu Yang, Zlatko Zlatev, Spyridon V. Gogouvitis, Gregory Katsaros, Kleopatra Konstanteli, George Kousiouris, Andreas Menychtas, Dimosthenis Kyriazis
Issue Date:May 2010
Cloud computing offers the potential to dramatically reduce the cost of software services through the commoditization of information technology assets and on-demand usage patterns. However, the complexity of determining resource provision policies for appl...
