Oracle Solaris Zones

The Oracle Solaris Zones software partitioning technology enables you to maintain the one-application-per-server deployment model while simultaneously sharing hardware resources.

Zones are virtualized operating environments that enable multiple applications to run in isolation from each other on the same physical hardware. This isolation prevents processes that run within a zone from monitoring or affecting processes that run in other zones, viewing each other's data, or manipulating the underlying hardware. Zones also provide an abstraction layer that separates applications from physical attributes of the system on which they are deployed, such as physical device paths and network interface names.

In Oracle Solaris 11.2, you can configure immutable root file systems.
