ZONE CONFIGURATION

Solaris zones provide virtual operating systems that look like different solaris instance to users and application.
zone allow the root user of the global zone to dedicate system resources to individual zones.each zone maintains their own root password and user information,separate from other zones and the global systems.Each zone exists with separate process and file system space and only can monitor and interact with local processes.
ZONE FEATURES:--
1) Security
2) Isolation
3) Virtualization
4) Granularity
5) Transparency

ZONE TYPE
Two types of zones
1) Global zone (Default zone) ZONE ID 0
2) Non-global zone

ZONE DAEMONS
1) zoneadmd:- primary process for managing the zone virtual platform. this deamons responsible for zone booting & shutting down. allocate zone ID and start zsched system process. setting zone-wide resource controls. plumbing virtual network interface & mounting loopback and conventional file systems.
2) zsched :- this process enables the zone subsystem to keep track of per-zone kernel threads.
