When to Use Zones
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.
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
Zones allow you to delegate some administrative functions while maintaining overall system security.
