I’m starting to see some big potential for symbiosis between two Linux and open source leaders: Red Hat and Ubuntu. Red Hat’s departure from the consumer desktop Linux market comes at the same time Ubuntu continues rolling in the same market with the release of Ubuntu 8.04 Hardy Heron this week. The latest Ubuntu also comes in a server version that continues distributor Canonical’s aspirations for enterprise servers. While it has been a struggle to sign OEMs for pre-installation, Canonical appears to be on the right track with regard to certification from the biggies. Still, Ubuntu’s server challenge is a big one, and it comes in a Linux market where Red Hat rules the roost.
