Yes. VMWare VMotion and Xen Live Migration are both VM migration tools, not containers.
The difference is subtle, but important. VMs have overhead because of virtualizing the kernel, Containers don't (or rather containers benefit from kernel performance much more than VMs).
In other words, you can achieve the same thing with VMotion, but it's slower and more overhead and harder to manage.
- stephenr 12y agoAh I didn't even know you're a container based shop. So you're moving live containers between aws provided xen vms.
- josh2600 12y agoOr on Bare-metal. It works just the same on Xen but slower because of the VM overhead. Containers are really only part of the solution, there's a lot of other things you have to think about if you want to build a better mousetrap in the virtualization world (like networking and storage).
