UnitedHealth & Amazon
UnitedHealth Group uses Amazon Web Services as a major cloud infrastructure provider for its Optum technology division, which processes claims, provides pharmacy benefit management, and delivers analytics for the US healthcare system. AWS handles significant data processing workloads for Optum's care management and population health platforms.
Why it matters: UnitedHealth is the largest health insurer in the US with $400B+ in annual revenue (2024). Optum, its technology and pharmacy arm, generates $250B+ in revenue and is the largest employer of physicians in the US. Modernizing Optum's data infrastructure on AWS enables real-time claims processing, fraud detection, and care gap identification at scale.
