'''IBM AIX Workload partitionsPartitions''' ('''WPARs''') are a software implementation of [[OS-level virtualization|operating system-level virtualization]] technology introduced in the [[IBM|IBM's]] [[IBM AIX|IBM (operating system)|AIX 6.1 operating system]] that provides application environment isolation and resource control.

WPARs are software partitions that are created from, and share the resources of, a single instance of the AIX OS. WPARs can be created on any [[systemIBM Power Systems]] or [[IBM System p]] hardware that supports AIX version 6.1 orand higher versions.<ref>[https://www.theregister.com/2012/02/17/ibm_aix_5_3_i5_v5r4_support/ "IBM puts AIX 5.3 on extended life support"] ''The Register''. Retrieved 2024-04-17.</ref> There are twothree kinds of WPARs,: System WPARs; Application WPARs; and ApplicationVersioned WPARs.

Line 9 ⟶ 11:

==Application WPAR==

Application WPARs are light weightlightweight environments used for isolating and executing a single application process.

==Versioned WPAR==

A WPAR which contains an instance of either AIX 5.2 or AIX 5.3. Versioned WPARs are only supported in AIX 7.1 and later LPARs.
