The classic system administration changed a lot in a decade.
Virtualization and container technology went through a remarkable improvement.
They have a stable place in the systems:
- Virtual machines run almost isolated from the host system.
- Containers sit on the top of the same kernel bringing a lightweight separation.
FreeBSD Jails don’t compete with containers.
They don’t substitute virtual machines.
Jails just fill a gap.
