Case Study: Largest Not-for-Profit Healthcare Organization achieves 40% Mainframe Cost Reduction and $50M Savings with Ensono Mainframe-as-a-Service

Health Insurer Future-Proofs Mainframe Workloads While Saving $50M

The Largest Not-for-Profit Healthcare Organization, one of the nation’s largest not-for-profit healthcare providers, needed to simplify mainframe maintenance and prepare for retiring staff while moving commercial workloads to AWS. It selected Ensono for mainframe expertise and used Ensono’s Remote Infrastructure Management, Remote Hosted Mainframe services, and Mainframe-as-a-Service (MFaaS) to support federal workloads that had to remain on the mainframe.

Ensono implemented a phased outsourcing plan, scaled hosted data center support for delayed migrations, and refreshed hardware to improve performance and security. As a result, the organization achieved a 40% reduction in mainframe-related costs and is expected to save $50 million over five years, while maintaining reliable service and giving internal teams more time to complete the AWS migration.
