Even if the cloud.com domain name could fetch $7 million, it would still be well short of the $13 million paid last year for sex.com, which the as the top priced domain name sold in 2010.

The domain name social.com was sold for $2.6 million this month, the highest price so far this year in the Journal's listings.

But Citrix had motivations for buying Cloud.com that had little to do with the name.

Cloud.com's infrastructure management product enables users to take existing hardware and hypervisors and create a cloud platform. Its main product, CloudStack, provides orchestration, load placements and management features that make the task possible.

Peder Ulander, the chief marketing officer at Cloud.com, said that about 80% of the company's customers today use its products with Citrix Xenserver.
