- Linux on IBM Z and LinuxONE uses s390x architecture, supporting distributions like SLES, RHEL, and Ubuntu with thousands of tested software packages.
- An IBM team collaborates with open source projects to validate specific applications, ensuring they compile and run well; May 2026 validation covered Apache Cassandra, HBase, and others.
- The broader open source community saw enhanced s390x support in May 2026, with over 10 projects adding support, including Kuadrant, Terraform, and CI/CD updates.
- The Open Mainframe Project added builds for InfluxDB 3 Core and MySQL 8.4.8/9.6.0, with updates for Spire and Beats.
- Developers can access free virtual machines via the IBM LinuxONE Community Cloud for 120 days to test applications on s390x, or apply for permanent resources for CI and development.
