Last week we showed you how global computing helps CERN store, distribute and analysis around 25 Petabytes (25 million Gigabytes) of data generated per year from the Large Hadron Collider. In this Hangout we explored big data even further, and answered more of your big questions, along with IT experts from CERN and the Worldwide LHC Computing Grid (WLCG) project - a global collaboration of more than 170 computing centres in 36 countries.
