Interesting. I'd like to see a return to owning/renting whole machines and running containers on them directly (as several major tech companies do). A lot of the value proposition for the cloud service providers is a multi-host hypervisor that's really easy to get started with (compared to buying vSphere). If it becomes really easy to deploy your own instance of an open-source container scheduler across your own boxes, we can return to cost-competitive commodity boxes instead of overpaying for AWS.
