Containers "scoot" like virtual machines?
Lorna, Over at VMware, they're groaning at the notion that containers can "scoot between" servers the way virtual machines are "live migrated" between physical hosts. It  may be possible someday, but for now the systems management of virtual machines is far ahead of containers. Containers can be deactivated, moved over the wire and restarted, but that doesn't sound much like vMotioning a currently running VM. Both, however, can be moved from one destination to another as a set of files. VMs are non-discriminating; practically any host with the right hypervisor will do. Containers need to move between similar Linux kernels. It seems likely to me that containers will suggest new forms of workload movement and data center automation. It's just very early in deciding how to do it.

OS
That's a great explanation, that a container is tied to an external OS while VMs contain the OS. Are there any other dependencies that containers have? Or, as long as Server A and Server B both have the same version of RHEL, a container can scoot between them regardless of other factors?

a way to mitigate lock-in?
Do Docker containers make it easier to avoid lock-in with specific cloud vendors? Or is there something else that limits app portability between providers?
