Why Linux on Z?

The enterprise Linux® operating system offers a solid foundation for your hybrid cloud IT infrastructure. See how workloads running on Linux on Z inherit the reliability, scalability and security of the IBM Z® platform and how workloads consolidated onto Linux on Z share resources to reduce costs.


Run your Linux applications on IBM Z to inherit the capabilities of the platform.
