This helps some with the terminology.
https://blogs.oracle.com/orasysat/entry/shall_i_use_zones_or
At OOW, they announced some additional innovation with the introduction of
"Kernel Zones"
With kernel zones customers will have to option to run different kernel patch
levels across different zones while maintaining the simplicity of zones
management. We'll also be able to do live migration of kernel zones. All of
that across HW platforms, i.e. kernel zones will be available on both SPARC as
well as x86. Key benefits of kernel zones:
x Low overhead (Lots of optimizations because we run Solaris on Solaris)
x Unique security features: Ability to make them immutable by locking down the
root file system
x Integration with the Solaris resource management capabilities: CPU, memory,
I/O, networking
x Fully compatible with OVM SPARC as well as native and S10 branded zones
x Comprehensive SDN capabilities: Distributed Virtual Switch and VxLAN
capabilities

Yes, each zone is it's own separate environment. There is a global zone as well
that in our environment the DBAs do not have access to. Different technologies
but the end result is very similar to VMware or other virtualized environments.
From within a zone you cannot see the other zones or even know they exist.
We are on Solaris 10 and have seen some weirdness where at low loads some
utilities such as uptime and sar show results for the zone only (as they
should) but under high load show results for the entire physical server. Don't
know if that's been fixed in Solaris 11 or not.
