Linux on Z and containers
The same mainframe hardware that runs z/OS also runs ordinary Linux. Learn what IFLs and LinuxONE are, how z/VM and KVM host Linux guests, what s390x means for your software, how containers and OpenShift fit, and when Linux on Z is the wrong answer.
What you will be able to do
- Explain what Linux on IBM Z and LinuxONE are, and what an IFL is and why it exists
- Describe the ways Linux runs on the platform: directly in an LPAR, as a z/VM guest, or under KVM
- Identify what changes for software built for s390x, including containers and multi-architecture images
- Judge when co-locating Linux workloads beside z/OS helps, and when another platform is the better choice
Lessons
- Linux on the mainframe: IFLs and LinuxONEMainframe hardware can run ordinary Linux distributions alongside, or instead of, z/OS.
- Hosting Linux: LPARs, z/VM, KVM and s390xLinux on Z can run directly in an LPAR or as a virtual guest under z/VM or KVM. Software must be built for the s390x architecture, which is 64-bit and big-endian, so most…
- Containers, OpenShift and co-location with z/OSContainers and Kubernetes run on Linux on Z just as on other platforms, as long as images are built for s390x.
