What single IT element will have the greatest
effect on IT Infrastructure and Operations
during the next few years?
 “Virtualization,” according to Gartner VP
and Distinguished Analyst Jay Pultz.

Symposium/ITxpo, 2006
IDC estimates that nearly 500,000 server boxes
equipped with virtualization software will ship this
year, up from just above zero three years ago. By
2009, the number of units shipped is expected to
reach 1.2 billion, the research firm said. – Sept 2006
