What is a Solaris Zone?
A Solaris Zone is a virtual environment that has security and application fault containment, and its own name space that can be tailored to the application that will run in it. It is possible to give a Solaris Zone its own node name, IP address(es), users, groups, disk space, network ports, name server, and so on. The security and fault containment mean that users working inside the Solaris Zone have no way to compromise or even look out of their own environment other than what would be the case with separate systems—through the network or shared disk.
