Diane Greene

If virtualization is one of the hot technologies to watch for in 2007, then VMware President Diane Greene may have the best seat in the house.

Greene, along with her husband and three other engineers, founded VMware in 1998 as a company that could take the concept of virtualization—the ability to run multiple applications and operating systems on a single server or PC—and develop the technology for a much wider audience.

VMware, which is owned by EMC, dominates the virtualization field and had a record year in 2006, including an 83 percent increase in revenue over the previous year. VMware announced earlier this year that it will sell 10 percent of the company in an initial public offering, which means that customers will likely see more in the way of virtualization innovation in the coming years. ´
