Solaris zones is a low overhead virtualization technique, where the guest system is using the same kernel as the underlying systems.

Solaris zones are process teams running in a changeroot environment on the underlying hosting Solaris system, called "Global Zone".

Global Zone
- hosting Solaris instance with access to all physical ressources.
- All processes belonging to nonglobal (hosted) zones are visible from within the global zone.

Nonglobal Zone - Solaris Process Container appearing as a separate system to processes running inside of it.

Branded Zone (BrandZ)
- with an added layer of system call translation, it is possible to run a different operating system revision within a Zone.
