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) makes it possible to run Linux on IBM Z

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.


  • This class is intended for z/OS system programmers and IT specialists in
  • charge of configuring, implementing and deploying zCX under z/OS 2.4
  • - This class is also intended for Application developers who will deploy docker
  • containers in a zCX z/OS container extensions instance

Thinking about Onsite?

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. Its a cost effective option. One on one training can be delivered too, at reasonable rates.
