Red Hat OpenShift on IBM Z and LinuxONE

IBM Cloud Organizations face the challenge of delivering extraordinary customer experiences by developing new applications, while modernizing existing applications to speed up their cloud-native journey.

Red Hat® OpenShift® on IBM zSystems and LinuxONE empowers organizations to accelerate transformation with greater flexibility and agility through integrated tooling and a security-focused and resilient foundation for cloud-native development.

Cloud Native development

The Red Hat OpenShift Container Platform subscription includes several capabilities that are enabled for IBM zSystems and LinuxONE:

  • Red Hat OpenShift Service Mesh, built on Istio, provides a uniform way to connect, manage, and observe microservices-based applications as managing and security between services become more difficult.
  • Red Hat OpenShift Pipelines, a cloud-native, continuous integration and continuous delivery (CI/CD) solution based on Kubernetes resources.
  • Red Hat OpenShift Serverless, a serverless cloud computing model providing developers with a modern, cloud-native app dev stack for hybrid clouds. Serverless lets developers focus on their code without worrying about the infrastructure.
  • Red Hat OpenShift Do (odo) is a command-line interface tool for writing and deploying applications on OpenShift and Kubernetes, allowing developers to focus on what’s most important to them—code.

Security

Red Hat OpenShift on IBM zSystems and LinuxONE allows businesses to integrate and modernize their applications with a firm foundation built for security, resiliency, and availability.

IBM zSystems and LinuxONE prevent security threats and protect data across a hybrid cloud environment with certified multitenant workload isolation and a transparent, pervasive encryption with optimized performance.

IBM zSystems and LiunxONE also protects the integrity and confidentiality of data with Crypto Express adapters (HSM) designed to meet strong security requirements of FIPS 140-2 Level 4, have quantum-safe cryptography embedded, and support compliance to regulatory guidelines efficiently and productively.

Co-located workloads

Cloud-native applications can be located close to existing workloads to improve throughput and reduce latency, empowering organizations to integrate and modernize without disrupting current services along their cloud-native journey.

For more information, see LinuxONE Co-location pattern article in this wiki.

Infrastructure and installation

Kernel-based Virtual Machine (KVM) is a fully supported virtualization option on IBM zSystems and LinuxONE for OpenShift users, alongside the traditional IBM z/VM hypervisor.

Running user provisioned infrastructure (UPI) installs of Red Hat OpenShift using KVM via libvirt on IBM zSystems and LinuxONE are supported. For environments provisioned using IBM Cloud Infrastructure Center, which provides the Infrastructure-as-a-Service (IaaS) layer on IBM zSystems and LinuxONE, the platform-agnostic installer should be used.

z/OS Cloud Broker

IBM z/OS Cloud Broker enables OpenShift applications to easily interact with data and applications on IBM Z.
