Is PaaS a feature of a cloud or gateway to a cloud?
Is PaaS just a feature of infrastructure as a service? Reuven Cohen made that argument convincingly here: http://www.informationweek.com/cloud/platform-as-a-service/cloud-crossroads-which-way-paas/d/d-id/1114123?
Or is it the other way around. The best way to access cloud infrastructure is through a PaaS. For the enterprise, I think it's this prospect that has long term appeal, though I don't know that all enterprise IT shops think this way. It takes a DevOps mindset and that's still a suspect proposition in some cases. Despite disadvantages at the moment, Red Hat is in a position to deliver on OpenShift as a way to build RHEL applications in the cloud and deliver RHEL applications to the cloud. Will it still strive to do so through an OpenStack project, with its former compatriots defecting to Cloud Foundry? I don't know. I'm thinking Krishnan Subramanian may offer part of the answer in another contributed IW column soon.
