Citrix, one of the major players in the hypervisor space, reported year-over-year revenue growth in the final quarter of 2009. Company executives said products across all segments gained market share, including solutions targeted at the data center space.

Reporting growth in demand for Citrix's solutions for data centers, the company's CEO Mark Templeton said in a conference call that its XenServer virtualization platform was currently running in data centers of about 40,000 organizations around the world. Of these, the largest organization has deployed the hypervisor on at least 20,000 physical servers.

Providing virtualization solutions for the data center space is one of three major focus areas for Citrix, in addition to desktop virtualization and collaboration technologies.

The company's second major product targeted at the data center and cloud computing space is NetScaler, a Web application delivery controller. Citrix CFO David Henshall said both server virtualization and NetScaler product lines were gaining market share, cumulatively driving more than 50 percent of the company's revenues.

Also up were revenues from the company's Software-as-a-Service business.

Overall, Citrix reported a GAAP net income of $88 million during the fourth quarter of 2009, an increase from $60 million it reported in the fourth quarter of 2008. Comparing the same two quarters, its new product license revenue increased by four percent and license update revenue grew six percent.

Online service revenues jumped 18 percent and revenue from technical services grew by 20 percent.

Citrix's total non-GAAP revenue in the fourth quarter of 2009 was about $451.2 million, up from about $415.7 million one year ago.
