WellSpan Health is a leading healthcare system serving Central Pennsylvania and Northern Maryland.
“Sublimation handled the EHR upgrade and migration work exceptionally well, bringing the right expertise, discipline, and partnership to one of the most critical parts of our cloud journey.”
— Darin Prill, VP & CTO, WellSpan Health
WellSpan Health’s traditional, on-premises data center model constrained its ability to scale technology, adopt AI-driven capabilities, and deliver timely clinical insights. The organization also faced significantly higher enterprise virtualization licensing costs, which became a catalyst for its cloud modernization effort.
The health system needed a transformational path forward—one that could unify its data environment, enable rapid deployment of AI applications, and support the speed and scale required by a growing integrated care network serving 1.2 million patients.
WellSpan selected AWS as its preferred cloud provider and Sublimation Health to migrate its EHR environment end-to-end with specialized depth, precision, and speed.
Our team transitioned all applications, data, and IT environments from on-premises data centers to AWS with a migration strategy built around five key capability pillars:
Specialized clinical applications across departments—including nursing, cardiology, pharmacy, and supply chain—were migrated to AWS, replacing fragmented legacy systems with a centralized, standardized cloud environment.
The migration plan was carefully designed to execute within an accelerated timeframe without sacrificing stability. Sublimation Health completed the migration in 17 weeks, making it the fastest EHR cloud migration of its size and scale executed in the healthcare sector.
Cloud architecture introduces a highly secure, compliant, and elastic infrastructure that dynamically scales computing resources to handle seasonal demand fluctuations and supports rapid deployment of new services across multiple locations.
As a key measure of success, migration delivered a 70% reduction in time to value, and a 229% faster completion rate compared to typical implementation timeframes.
Leveraged advanced Infrastructure as Code (IaC) frameworks for highly elastic infrastructure provisioning on AWS, supporting evolving technical and operational requirements with precision and consistency.
Developed and deployed server fleet automation and data harmonization techniques that reduced environment setup and configuration timelines by approximately 60–70%, improving readiness across development, testing, and production environments.
Innovated snapshot and cloning functionality that minimized downtime and operational overhead while enabling efficient execution of backups, restores, and full EHR environment refreshes in compressed timeframes.
“This was never an IT project. The impossible was achieved because it was an organizational transformation driven by mission aligned vision from the very top.”
— Jeremy Marut, CEO, Sublimation Health
The AWS migration establishes a sustainable, scalable foundation for data-driven innovation across WellSpan’s care network. The organization now has the agility to deploy next-generation clinical capabilities at speed and at scale—from AI-assisted imaging to automated administrative workflows.
As a result, WellSpan has exited the data center business. Running its EHR and integrated ecosystem natively on AWS eliminates the operational burden of on-premises hardware, reduces infrastructure risk, and delivers enterprise-grade reliability at a lower cost.
The health system now operates in a unified, scalable data environment purpose-built for AI and advanced analytics. Clinical intelligence, predictive insights, and population health tools are ready for deployment today.
With infrastructure no longer a daily concern, clinicians regain time for patient care while engineering teams focus on innovation. The AWS-based EHR ecosystem accelerates diagnostic workflows, reduces administrative friction, and returns thousands of hours annually to patient-facing care. WellSpan key benefits are:
