OpenStack Icehouse release takes on enterprise upgrade concerns

The OpenStack IceHouse release due this week promises more business-friendly enhancements including at least some support for rolling upgrades from the previous (Havana) release.

As Red Hat product manager Steve Gordon wrote in a blog post last month:

“The Compute services now allow for a level of rolling upgrade, whereby control services can be upgraded to Icehouse while they continue to interact with compute services running code from the Havana release. This allows for a more gradual approach to upgrading an OpenStack cloud, or logical designated subset thereof, than has typically been possible in the past.”

If this works as promised — although unclear what “a level of rolling upgrade” means, it could be a big advance for OpenStack which has been dinged for the difficulty of upgrades – which required complete system shut down — something no IT person wants to even consider. Gigaom Research analyst Paul Miller has more on architecting OpenStack for the enterprise. 

Expect more OpenStack news to emerge in the run up to the OpenStack Summit in Atlanta next month but rivals aren’t standing still: Apache CloudStack recently announced its 4.3 release with Hyper-V support. And Eucalyptus continues to push its Amazon-compatible private cloud infrastructure
