How John Hancock revolutionized its mainframe insurance admin on AWS
summary
John Hancock moves its mission‑critical annuities stack from mainframe to AWS in 13 months, rehosting Vantage/WMA and a legacy payout system so that a 400‑MIP mainframe with ~2 million lines runs in cloud with functional and performance parity. DXC/DXE uses Micro Focus replatforming, containerized COBOL, AWS M2/Blue Edge and Precisely for replication, exposes 30+ APIs (initially 11–12 used), consolidates three payout systems to one and cuts TCO while keeping operations seamless.
