ESX0G - IBM z/OS Container Extensions zCX

z/OS Container Extensions (zCX), a new entitled capability of z/OS 2.4, ushers in a new era of hybrid computing supporting running Linux applications directly on z/OS.

IBM® z/OS® Container Extensions (IBM zCX) make it possible to run Linux on IBM applications that are packaged as Docker container images on z/OS. Application developers can develop and data centers can operate popular open-source packages, Linux applications, IBM software, and third-party software together with z/OS applications and data.
