Why z/OS?

Digital transformation has become ubiquitous – driving higher data and transaction volumes and accelerating the rate of application changes. Hybrid IT architectures rely on off-premises and on-premises IT resources, producing challenges in capacity, scale, availability, and throughput.

The IBM® z/OS® V2.3 operating system delivers the highly scalable and secure next-generation infrastructure hybrid architectures require. IBM z/OS offers extreme performance, availability, scale, I/O support, and security – on premises, off premises, or provisioned as-a-service – for the trusted, real time reaction to business opportunities.
