I hope that your post is an April Fools joke. We've been running our company on OpenStack for the last year (longer if you count Rackspace's OpenStack-based public cloud) and it's been awesome. I gave a presentation on it last night at the Seattle DevOps meetup: https://speakerdeck.com/chrissnell/so-long-public-cloud https://speakerdeck.com/chrissnell/so-long-public-cloud EDIT: In response to your edit (companies that sell OpenStack), I also disagree! OpenStack is still a bit of a bear to maintain and upgrade. It requires a lot of specialized knowledge and many companies that might leverage it may not because of the amount of time required to set up and maintain the infrastructure. We utilize a managed OpenStack cloud at Rackspace. For various reasons, building a collocated cluster based on Nebula was not evaluated as a hosting option for us but it might have been viable. I think there's a market for easy-to-operate OpenStack and I'm not sure why Nebula failed. I'm guessing (based on some other comments here) that there's more to the story.
