Often seen as competing, containers a la Dockers and hypervisor a la Xen are more complementary than enemies !
By using both technologies we can be more efficient.
let’s see some examples. Dockers mains advantages are a fast boot, simple usage, little (or no) overhead and high density per host but they rely on same kernel/OS which is bad for security and isolation., and well, some “battle” between devs and ops
ON the other side, Xen let’s you have different OS/kernels, have more overhead and have a more traditional/mature approach.
Why not use both world ?
Let VM run in a hypervisor with a define set of resources. it offer you (dev) rollback, snapshot and so on easily, considering it as a sandbox.
For the sysadmin, and easy way to handle/extend/replicate resources of VM, even in live with some hypervisor.
