Why z/OS
IBM z/OS® is designed to keep applications and data available, systems secure, server utilization high, and development agile. It maintains compatibility for existing applications and runs Linux® on IBM Z® containers on premises and in hybrid clouds. And with the new IBM z15™ you can get even more performance, data privacy, security, and cyber resiliency.
