               Weather forecast: Will
             it rain Grids and Clouds?
     Bernhard Schott of Platform Computing believes that not only is business ready for the Grid and the
     Grid ready for business, but that it is wise to invest in this technology now, despite the
     economic downturn, as there is money to be saved in the long term as well as efficiencies to be gained
