The Clingan Zone

The Clingan Zone: " implementation is neither like VMWare/VirtualPC nor IBM Mainframes. VMWare/Virtual PC emulate hardware. IBM's LPAR abstract out the hardware but you are running essentially in a virtual machine. Zones are lighter weight, much more scalable and are a good choice for application consolidation. Both of the above virtual machine models require a running operating system per virtual machine. This is quite a bit of overhead. Solaris zones do not run a seperate instance of an operating system. From a developer (and to a lesser degree administrator) perspective it feels like its own seperate Solaris instance, but there is really only one instance of Solaris running."
