The Solaris Zones partitioning(software partitioning) technology is used to virtualize operating system services and provide an isolated and secure environment for running applications. A zone is a virtualized operating system environment created within a single
instance of the Solaris Operating System.
When you create a zone, you produce an application execution environment in which processes are isolated from the rest of the system. This isolation prevents processes that are runningin one zone from monitoring or affecting processes that are running in other zones. Even a process running with superuser credentials cannot view or affect activity in other zones.<\/p>\n

A zone also provides an abstract layer that separates applications from the physical attributes of the machine on which they are deployed. Examples of these attributes include physical device paths.
Zones can be used on any machine that is running at least the Solaris 10 release. The upper limit for the number of zones on a system is 8192. The number of zones that can be effectively hosted on a single system is determined by the total resource requirements of the application software running in all of the zones.
There are two types of non-global zone root file system models: sparse and whole root. The sparse root zone model optimizes the sharing of objects. The whole root zone model provides the maximum configurability.
Zones are ideal for environments that consolidate a number of applications on a single server.
The cost and complexity of managing numerous machines make it advantageous to consolidate several applications on larger, more scalable servers.<\/p>\n

The following figure shows a system with four zones. Each of the zones apps, users, and work is running a workload unrelated to the workloads of the other zones, in a sample consolidated environment. This example illustrates that different versions of the same application can be run without negative consequences in different zones, to match the consolidation requirements.
Each zone can provide a customized set of services.
Zones enable more efficient resource utilization on your system. Dynamic resource reallocation permits unused resources to be shifted to other containers as needed. Fault and security isolation mean that poorly behaved applications do not require a dedicated and under-utilized system. With the use of zones, these applications can be consolidated with other applications.
Zones allow you to delegate some administrative functions while maintaining overall system security.<\/p>\n

l (Solaris 10 06\/06) Support for the ZFS file system, including the ability to add a dataset
resource in a native non-global zone, has been added. (UFS, ZFS \ud30c\uc77c\uc2dc\uc2a4\ud15c \uc0ac\uc6a9\uac00\ub2a5)
l (Solaris 10 11\/06) Support for configurable privileges has been added.
l (Solaris 10 08\/07) Support for the following features has been added to the zonecfg
command:<\/p>\n

\u25a0 Better integration of resource management features and zones. The zonecfg command can
now be used to configure temporary pools, memory limits, the default scheduling class for
the zone, and resource control aliases. You no longer have to perform any manual steps to
set up resource management.New resource controls were added:
    \u25a0 zone.max-locked-memory
    \u25a0 zone.max-msg-ids
    \u25a0 zone.max-sem-ids
    \u25a0 zone.max-shm-ids
    \u25a0 zone.max-shm-memory
    \u25a0 zone.max-swap
    \u25a0 Ability to use the zonecfg command in the global zone.
    \u25a0 Ability to specify an IP type for a zone. The two IP types available for non-global
zones are shared-IP(\ubb3c\ub9ac\uc801\uc778 NIC\uc758 \uac00\uc0c1 \uc778\ud130\ud398\uc774\uc2a4 \uc124\uc815) and exclusive-IP(\ubb3c\ub9ac\uc801\uc778 NIC\ub97c
Zone\uc774 \ub3c5\ub9bd\uc801\uc73c\ub85c \uac00\uc9c0\uace0 \uc124\uc815).<\/p>\n

\u25a0 Ability to useDTrace in a zone by adding required privileges through the limit priv
property.<\/p>\n

\u25a0 Ability to use boot arguments in a zone through the bootargs property.
l (Solaris 10 10\/08) The defrouter property has been added to the net resource in the zonecfg
utility for shared-IP non-global zones. You can set the default router for the network
interface through this property.
