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.
