The Solaris zones facility is a major step forward in the Solaris Operating Environment. It allows virtualization of Operating System services so that applications can run in an isolated and secure environment. Previously, this functionality has only been available on high-end, extremely expensive servers. One of the advantages of zones is that multiple versions of the same application can be run on the same physical system, but independently of each other. Solaris zones also protects the user from having a single application able to exhaust the CPU or memory resources when it encounters an error.
This chapter has described the concepts of Solaris zones and the zone components as well as the types of zone that can be configured.
You have seen how to configure a zone from scratch, and install and boot a zone. You also learned how to access the zone console, and login to a zone for system administration purposes.
