Who can benefit

Consider DXC Mainframe as a Service for your business if:

You are providing IT services in industries such as finance, healthcare and transportation, which heavily rely on mainframe systems for critical business operations; this increases the challenges related to managing and maintaining on-premises mainframe infrastructure.
You must reduce high capital expenditures and increase scalability. DXC, for example, helped a leading global logistics company reduce their cost of operations by 68% through modernization and mainframe exit.
You are losing talent with mainframe knowledge as older workers retire, and the next generation is not ready or not interested in becoming experts in this branch of IT.
You need to better align IT systems to the business and provide a more efficient application architecture.
