f Grid and Cloud Computing: Opportunities and challenges for e-Science

A new science paradigm has emerged in the last few years referred to as electronic Science (e <br>Science). It extensively uses simulation techniques based on software modeling which run on <br>distributed computing infrastructures. In addition, it makes use of huge amounts of distributed and <br>shared data captured by instruments or sensors and/or stored in databases, analyzed to provide new <br>results for science. This distributed HPC and data environment allows sharing the acquired <br>knowledge, accessing remote resources and enabling world wide scientific collaboration.
