A Solaris Zone is a technology that can logically separate one server into multiple independent partitions and that can build multiple virtual Solaris environments within a single server. It is possible to run various applications on each partition as a separate system. (software partitioning technology)
The software partitions where the virtual Solaris environments run are referred to as non-global zones, whereas the environment enabling these software partitions is referred to as the global zone. The redundant line control function ensures network high-reliability on non-global zones.
