At first glance, Canonical is an operating system company — built around Ubuntu Linux. But take a closer look at Canonical’s moves during the first half of 2009, and you’ll find the company has increasingly bet its revenue stream on cloud, online and consulting/support services.

Still, the potential Oracle-Ubuntu partnership gets a little sexier when you throw OpenOffice into the mix. Not even Jack, Janet and Chrissy looked this good together in their prime. Here's why.

If you want to use Ubuntu Linux servers, and the idea of saving money by running your servers on a cloud sounds interesting, boy does Canonical have a deal for you.
