Geisinger’s full-scale migration to AWS via self-funding
summary
Geisinger moves its entire IT footprint to AWS using a self-funding model that pays for migration with pre-migration savings (application rationalization, infrastructure cuts and AWS credits) and targets 90%+ cloud from ~10% while cutting infrastructure by ~40% and consolidating ~1,500 apps to ~1,100. The program builds a migration factory with wave-based non‑prod first moves, re‑architects EHR DR to spin up resources on demand, trims Citrix servers, trains staff and expects millions in TCO savings and improved agility.
