VMware, Inc. is an American software company that provides cloud and virtualization software and services. It was founded in 1998 and based in Palo Alto, California, USA. The company was acquired by EMC Corporation in 2004, and operates as a separate software subsidiary.
VMware's desktop software runs on Microsoft Windows, Linux, and Mac OS X, while VMware's enterprise software hypervisors for servers, VMware ESX and VMware ESXi, are bare-metal embedded hypervisors that run directly on server hardware without requiring an additional underlying operating system.
In 1998, VMware was founded by Diane Greene, Mendel Rosenblum, Scott Devine, Edward Wang and Edouard Bugnion. Greene and Rosenblum, who are married, first met while at the University of California, Berkeley. Edouard Bugnion remained the chief architect and CTO of VMware until 2005, and went on to found Nuova Systems (now part of Cisco). The company has its headquarters in Palo Alto, California, United States, and established an R&D Center in Cambridge, Massachusetts, as well as one at the Time Warner Center in New York City, in 2005. VMware operated throughout 1998 in stealth mode with roughly 20 employees by the end of that year. The company was launched officially in February 1999 at the DEMO Conference organized by Chris Shipley.
