A recent Greenwich Associates (GA) report discussed, in connection with the use of cloud computing by hedge fund managers: what hedge fund managers use cloud computing for, security, compliance and culture.  The report concludes with a four-part argument in favor of the ability of hedge fund managers – especially those that use derivatives or structured products – to obtain more computing power at lower cost via the cloud.  This article summarizes the GA report.  See also “Key Considerations for Hedge Fund Managers in Evaluating the Use of Cloud Computing Solutions (Part Two of Two),” Hedge Fund Law Report, Vol. 5, No. 41 (Oct. 25, 2012).
