IBM Z® mainframes run on z/OS®, Linux®, and z/TPF, with multiple operating systems (OS) often running on a single mainframe. IBM z/VM® and KVM are hypervisors designed to run Linux, z/OS and z/TPF virtual machines (VM) as well as Red Hat® OpenShift® on IBM Z and LinuxONE servers.
Each operating system and hypervisor have unique characteristics that bring the security, resiliency and agility of the mainframe platform to your hybrid cloud.
Grow and future-proof your skills with training for z/OS, Linux, z/VM and more.
Unleash the power of your developers to rapidly launch new services for hybrid multicloud.
Keep data protected and encrypted across your enterprise and hybrid multicloud environment.
Gain availability and flexibility to meet workload demands regardless of your capacity needs.
Mainframe operating systems
z/OS for security and flexibility
Get an operating system ready to run mainframe apps and Linux containers with high availability, utilization, agility, and security.
Linux for open source agility
Enterprise Linux delivers security, efficiency and performance to your Linux and container workloads on premises and in hybrid clouds.
z/TPF for transaction processing
Process high transaction volumes — such as credit cards and airline reservations — in near-real-time with an operating system designed for the quality service of the mainframe.
Hypervisor operating servers
z/VM hypervisor for virtualization at scale
Run thousands of Linux on Z virtual machines on one system – as well as z/OS and z/TPF — with reliability, performance, system management and security for your applications.
KVM for an open source hypervisor
This strategic open source component for the IBM Z and IBM LinuxONE platforms is offered through our Linux distribution partners to help simplify ordering.
