Boost innovation with this powerful combination of agility, security, scalability, and containerized software.


My role at IBM is to make sure that we’re equipping developers with the tools and resources you need, along with the selection and guard rails you prefer, to help you focus your efforts entirely on innovation. Security is key to unlocking the true value of the cloud, and we want that to be one less thing you have to worry about when you’re building high-performance solutions. To that end, this week we announced a major milestone furthering Kubernetes support for Linux on IBM Z and IBM LinuxONE: The Red Hat OpenShift Container Platform for Linux on IBM Z and LinuxONE is now generally available.

Kubernetes has been available on Linux on IBM Z and LinuxONE for some time and is detailed in this LinuxONE whitepaper. This has already enabled customers to start integrating Kubernetes-based microservices running on Linux on IBM Z and LinuxONE into their infrastructures, as well as the vast ecosystem of projects surrounding Kubernetes itself.

With this launch, developers can now access a platform with Kubernetes-based tooling, plus fast, built-in security and hardware-driven cryptography, high uptime and resiliency, fast access to your data, and everything else you’ve come to expect from Linux on IBM Z and LinuxONE. This opens the door to easier integration with existing solutions that are already using OpenShift in hybrid and multi-cloud models — whether your infrastructure resides on public or private clouds, or a combination. It’s our latest enhancement to help you truly build once, deploy anywhere.

Additionally, the IBM z/OS Cloud Broker allows OpenShift applications to easily interact with existing data and applications on z/OS. You will be able to use the IBM Cloud Infrastructure Center, an Infrastructure-as-a-Service (IaaS) that provides simplified infrastructure management of z/VM-based Linux virtual machines on Linux on IBM Z and LinuxONE. OpenShift is a platform-as-a-service (PaaS) and container-as-a-service (CaaS) layer that requires an underlying IaaS layer, which the IBM Cloud Infrastructure Center provides for IBM Z and LinuxONE.

OpenShift availability on the Z architecture allows for easier development of applications that work across your infrastructure. Microservices-based workloads that you develop can be managed as you see fit. Plus, with the IBM Cloud Pak for Applications, you’ll have access to a collection of tooling to help drive modernization efforts by leveraging DevOps-related tooling like IBM UrbanCode and enterprise-level support for Java, Node.js, Spring, and other runtime environments. With this release, for the first time, Red Hat Enterprise Linux CoreOS (RHCOS) is available for the Linux on IBM Z and LinuxONE platforms.

We’re helping you build smart, and build secure.

This release is primarily for evaluation, dev, and test, so we’re eager for you all to check it out. Get involved now to start testing your workloads in anticipation of production readiness, planned for later this year. Initially, you will need z/VM to implement OpenShift on the platform as virtual machines managed by IBM z/VM, with other options coming later. We’re also working on support for HiperSockets, SMC-D, Installer Provided Infrastructure (IPI), and persistent storage other than NFS, and you can expect support for all of these things down the line.

I invite you to join our webinar on March 5 to learn how the agility of OpenShift, the security and scalability of IBM Z, and the containerized software of IBM Cloud Paks are enabling innovation.
