Amazon hosts 6 to 8 of top 10 games on Facebook, including FarmVille.  That helped AWS generate $500 MIL in revenue for 2010.    Amazon's growth has had some bumps, with users occasionally unable to login to FarmVille.  Even so, AWS will see huge growth according to UBS analysts Brian Pitz and Brian Fitzgerald.  Their estimates: $750 MIL in 2011, $2.5 BIL in 2014.
