Back in May, we learned that AlmaLinux 9 was released, with support for IBM zSystems and LinuxONE . AlmaLinux has two versions at the time of writing, 9.0 and 8.6. The zSystems and LinuxONE support was only for 9.0 until recently due to the way that that AlmaLinux is built.

IBM Z and LinuxONE are renowned for the advanced security they provide, and are used by financial, government and other organizations across the world. Encryption is provided at a hardware level in two main ways – using the on-chip CPACF crypto accelerator, and through the IBM Crypto Express adapter. The Crypto Express adapter itself provides two main capabilities – fast asymmetric (public/private key) encryption for data-in-motion, and tamper-resistant protection of keys through Hardware Security Modules. Together, these can help protect the vital assets of organizations in their datacenters – from e-commerce to government to banks and fintechs. Meanwhile, ...

The Linux Foundation's Open Mainframe Project Techincal Advisory Council recently approved the creation of a Linux Distributions Working Group for IBM Z and LinuxONE. We have a community here of users and contributors, and each distribution has their own resources and mailing lists, but there wasn't a real collaborative space for all of the Linux distributions to get together to solve problems and share solutions. This new working group seeks to change that. "The purpose of this working group is to oversee the health and maintenance of the s390x port of various Linux distributions to ensure that the s390x port remains a supported architecture for them ...

A rich IaaS platform - and an infrastructure for Red Hat OpenShift on IBM Z The traditional layer classification of cloud services is into Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). And while there are many more variants proposed today, this still provides a useful way of looking at cloud architecture, with each layer providing its own value as well as services that are used by the layer above. IBM Cloud Infrastructure Center provides the IaaS on IBM Z and LinuxONE, as well as providing the infrastructure platform for Red Hat OpenShift which provides the PaaS. And with the new version 1.1.4 now announced ...
