How a Fortune 100 firm seamlessly moved from mainframe to AWS
summary
MassMutual migrates two mission‑critical admin applications off the mainframe to AWS using DXC tools and AWS Mainframe Modernization (MAP funding, Direct Connect, automated code analysis), then runs parallel cutover with automated functional and data validation and containerized DevOps pipelines (Jenkins, artifact repositories). Results: ~40% cost savings, 15% faster time‑to‑market, support for campaign scale bursts, and a plan to move >90% of workloads while tackling a legacy 3270 app with tightly coupled dependencies.
