The document discusses moving healthcare data architecture to the cloud. It describes a large health system that implemented an enterprise data warehouse (EDW) on the cloud to provide cost savings and flexibility. This consolidated multiple clinical repositories and reduced infrastructure costs. It also describes an academic health center that integrated patient records across its organizations using a cloud-based EDW. This improved analytics and reduced operating costs by 50% while improving patient care. Both organizations benefited from the scalability, cost savings and innovation the cloud enabled for their clinical analytics and research.
