2025 Best In KLAS Public Cloud

Over the past three years, a growing number of healthcare organizations have started using public cloud providers for their Epic workloads due to the promised benefits of a cloud environment. In 2023, KLAS published a report exploring the decision-making process of organizations considering the public cloud for their Epic environment; since then, several organizations have gone live with their Epic cloud environment. As an update to last year’s insights, this report examines the viability of Epic in the cloud—looking at the success and scalability of cloud deployments, the strengths and weaknesses of Amazon Web Services (AWS) and Microsoft Azure, the benefits organizations have achieved, and the areas where third-party support is used to facilitate the cloud journey. Note: Data for this report was collected from May 2024 to August 2024. At the time of this research, around 30 healthcare organizations in North America were live with Epic workloads in the public cloud; all use either AWS or Microsoft Azure. For this report, KLAS interviewed 18 of those organizations, including 10 clients live with a full Epic production environment.

Approaches to Moving Epic in the Cloud 2023

21 March 23 | Emily Paxman and Mike Smith

The benefits of public cloud are promising, as many Amazon Web Services (AWS) and Microsoft customers (both provider organizations and vendors ) have noted in previous KLAS research. The first health systems using a public hyperscale cloud provider (e.g., AWS, Google Cloud Platform, Microsoft Azure) to support their EHR environment in the cloud have begun to go live, and interest in this approach is gaining momentum, particularly among Epic organizations. Most who are pursuing this path are just beginning their journey, but some are actively selecting their public cloud provider and planning next steps. KLAS recently interviewed 10 organizations who are considering moving part or all of their Epic environment to the cloud. This report shares which public cloud providers they are considering, what Epic environments they may move to the cloud, what goals and concerns they have, and what role third-party firms will play in the transition. Note: Epic reports having 6 customers with their full production environment in the public cloud, 97 customers with their full production environment in Epic’s private cloud, and the rest primarily on-premises.
