DCU joins €4.7 Million EU Cloud Project

Dublin City University (DCU) today announced it has joined a consortium of leading organisations and universities from the United Kingdom, Sweden, Ireland and Germany focused on using real-world data to optimize and make more efficient cloud computing.

Named ‘CACTOS’, the €4.5 million project seeks to address issues arising from the growth and complexity of cloud infrastructure. The Modelling and Simulation Research Group based in DCU Business School will lead the research and development of the simulation framework (known as CactoSim) which will validate the optimized models and evaluate the performance for management of hosting on the cloud.  The development of a CactoSim will allow for experimentation with and validation of the performance of the developed intelligent context-aware cloud topology optimization strategies in a scalable (or large/massive scale) simulated environment, offering significant benefit over the utilization of testbeds which would be costly, time-consuming and complex to perform.

Dr. James Byrne, Senior Researcher at the Modelling and Simulation Research Group based in DCU Business School, said:

Controlled and reproducible experimentation with resource performance scenarios and different workload mix can be enabled in CACTOS through the use of simulation. This will enable both cost and risk analysis to be performed, as well as the tuning of potential system bottlenecks.

Ultimately, it is hoped that by researching and developing the simulation toolkit within the CACTOS environment this will result in more robust optimisation algorithms and enhanced decision support for cloud infrastructure management. This will lead to cost savings and increased efficiency through the use of the CACTOS toolkit. Gaining access to large scale data centres can be an issue from both a cost and time perspective, and simulation will enable experimentation and evaluation on a large scale without requiring such access.


CACTOS is a collaborative research project co-funded under the ICT theme of the 7th framework programme (FP7) of the European Union.  For more information visit www.cactosfp7.eu.
