2007. Citrix to buy virtualization company XenSource



Citrix has acquired open-source virtualization company XenSource for about $500 million. Citrix makes so-called thin client software that delivers business applications from servers to desktop computers. By acquiring XenSource, the company intends to move into the adjacent server and desktop virtualization market. The company's open-source "hypervisor" software, called Xen, lets a single computer run multiple operating systems simultaneously, which is a useful way to replace servers with one, more efficiently used computer. XenSource's commercial offering, XenEnterprise, is based on the Xen software. Virtualization has become a hot technology in IT because it allows corporate customers to lower their computing costs by packing more computing jobs onto fewer computers. The virtualization market leader VMware went public yesterday, with its stock price shooting to $51 from its offering price of $29.
