The infrastructure benefits are completely there in terms of driving up utilization/density of the hardware you're buying. I feel (and know!) there will be a lot of optimization on making this happen.
On the other hand, there are some insecure multi-tenancy concerns for which VMs still offer better isolation. That's ok, because Docker is not about virtualization, it's about a platform for distributed applications.
Thus, finding the right/secure/optimal/? place to run your container should be straightforward and intuitive. That's the direction we're looking to take the industry.
