What are the top concerns that keep IT executives up at night? SIM (Society for Information Management) surveyed 172 C-level IT executives, including CIOs, Chief Technology Officers and CISOs (Chief Information Security Officers) to find out. Here, eWEEK presents the findings in a countdown of the 10 most important issues these high-ranking technology executives said they were facing in 2010. IT executives are facing business pressure like never before and are heavily scrutinized for return on investment in five major areas of technology. The five most invested areas (from 5 to 1) are cloud computing, business continuity/disaster recovery, virtualization, enterprise resource planning and business intelligence.
