The Increasing Cost of Red Hat Linux?

An Anonymous Coward asks: "I work at a company with a large number of Linux servers in the data center. We're currently evaluating what distribution we want to use moving forward. Upgrading to Red Hat Enterprise from 7.2 would cost ~$350k just for the systems we already have deployed. Due to the change in Red Hat's release policy, we either have to move to Enterprise, or change distributions. Also, we don't have Oracle on any of these systems, but we will need it in the future. This leaves us with rather limited options. I'm interested hearing what other Slashdot readers are running, and planning?"
