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, ...

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 ...
