More commonly called OS-level virtualization. A type of server virtualization technology which works at the OS layer. The physical server and single instance of the operating system is virtualized into multiple isolated partitions, where each partition replicates a real server.
Later, in the 1970s, the emergence of the virtual machine came about. With the virtual machine, an entire system (software and hardware) could be emulated in a contained environment.

These practices are often employed in data mining and data warehousing systems.
