IBM Z Content Solutions | Z/OS Container Extensions (zCX)

Q: Do application developers require knowledge of z/OS to create and deploy Linux on IBM Z applications to run in z/OS Container Extensions?

A: Applications will look like Docker applications to the developer, not z/OS applications. If your application comes from Linux on IBM Z, then no z/OS skills are required. Docker and Linux knowledge are all that is required.

Q: Does Container Extensions make use of Kubernetes?

A: No, not at this time. The initial release of zCX for IBM z/OS V2.4 provides Docker Swarm as support for Docker cluster management. IBM’s future plans intend to include Kubernetes clustering for the orchestration, scalability, and management of zCX with compatible cloud platforms.

Q: Will there be performance data published for zCX?

A: There is currently no plan to publish performance data for the zCX environment because performance is heavily reliant on individual configuration, workload, and networking characteristics.
