Mainframe as a service has been a game changer for DES. It increased our IT reliability and powered agile responses to the Covid-19 pandemic.

Business Challenge

To reliably support people in need, the Arizona Department of Economic security (DES) needs IT to be online 24x7. Unfortunately, the agency’s heritage mainframe experienced several extended outages, largely because the system was near its end of life and service contracts were expiring. The solution was to replace the system with the latest mainframe delivered “as a service” and managed by a service provider.


By engaging IBM Global Technology Services for the mainframe-as-a-service migration, DES gained considerable business value. The new platform is based on IBM Mainframe as a Service, which provides scalable IT designed for high availability—just what DES needs to deliver uninterrupted social services. Plus, the hybrid cloud platform fosters application modernization.
