Solaris Zones: Operating System Support for Server Consolidation.
ANDREW M. TUCKER, David Comay · 2004

Consolidation is already common in mainframe environments, where technology to support running multiple applications and even operating systems on the same hardware has been in development since the late 1960’s. Such technology is now becoming an important differentiator in other markets (such as Unix/Linux servers), both at the low end (virtual web hosting) and high end (traditional data center server consolidation).
