DXC Mainframe

Trust the largest independent mainframe services provider in the world to run, optimise and modernise your mainframe and enhance resiliency.

Keep mainframes running smoothly

Many enterprises depend on mainframes for secure, reliable and heavy-volume data processing. But managing mainframes takes ongoing investment in software, hardware, facilities and support, and it’s a challenge to manage the costs and maintain the necessary skills.

We run, operate and support your mainframe platform – from monitoring and remote infrastructure management to full-service management, including hosting, storage and disaster recovery.

More than 160 IBM z/Series mainframe platforms under management, running 715,000 MIPs 

Hundreds of successful mainframe migrations

Optimised mainframe environments

We lower your total costs by improving operations, security and processing efficiency and deliver the availability, stability and capacity you need. With predictable, volume-based pricing, you easily move from a capital to an operating expenditure cost structure.

Benefit from reduced risk with automation and standardised operational tools and processes, while meeting government and industry regulations.

Experts in modernising mainframes

Customers trust us to manage their applications running on mainframes, and benefit from 3,000 experts who manage these applications. We optimise core applications and have a strong mainframe heritage, but we do not box customers into the platform.

Maximise the benefits of migrating with our clear mainframe modernisation paths and a single contract across mainframe and cloud services, including MIPS elasticity.
