Mirantis and Canonical pledge OpenStack-Linux kumbaya (take that, Red Hat!)

Mirantis, the rabble-rousing OpenStack integrator-turned-OpenStack provider, is partnering with Canonical to make sure Canonical’s Linux distribution runs well on Mirantis OpenStack. The stated goal is to ensure that both Canonical’s Ubuntu Host and Guest OS are supported on Mirantis OpenStack, according to a FAQ provided by Mirantis.

The move contrasts with Red Hat’s stance that it will not support non-Red Hat OpenStack distributions running in Red Hat Enterprise Linux shops.

While that policy is not new, one reason companies look at OpenStack for cloud technology is to free themselves from too much reliance on one vendor. Red Hat is seemingly reinforcing the old bugaboo of vendor lock-in. Red Hat Enterprise Linux leads the market in (natch) enterprise Linux, and obviously wants to parlay that strength in cloud. And that has the other OpenStack players worried — and ticked off. Hence announcements like this one.

The topic of OpenStack deployment and support will come up at Structure in two weeks, where Red Hat CTO Brian Stevens will be on hand.

In its FAQ, Mirantis says it hopes this move will “encourage Red Hat to rethink [its] approach to RHEL support. In fact, Microsoft, the historical king of anti-competitive behavior, has an open SVVP program for certifying third-party virtualization technologies against Windows Server that can serve as a model for Red Hat and the OpenStack community at large.”

Ubuntu Linux is believed to be widely deployed in Amazon(s amzn) Web Services — although it’s not clear how many of those instances are active. An OpenStack Foundation survey in October found that Ubuntu constitutes 55 percent of workloads running in OpenStack.
