Epic in the Public Cloud 2024

07 November 24 | Chloe Jensen and Mike Smith

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.

Public cloud providers are increasingly important to how HIT vendors deliver software to provider and payer organizations. To help HIT vendors make informed decisions about which public cloud provider can best meet their needs, this report examines (1) how industry adoption of public cloud solutions is progressing and (2) how well public cloud providers perform in key areas, including their strengths and improvement opportunities.

While still early, healthcare is gaining momentum in the move to the cloud. Today, most providers and payers are at least using SaaS technologies, and many are actively exploring other areas of their IT environment that make sense to move to the cloud. This report—the second in a series examining healthcare customers’ experiences with public cloud providers—focuses on healthcare-specific deployments of Microsoft Cloud Technologies , especially Microsoft Azure, which is receiving strong market interest. KLAS previously published research on AWS and plans to publish future research on Google Cloud Platform (GCP). For this study, KLAS spoke to eight healthcare organizations (during late 2021 and early 2022) identified by Microsoft as leading cloud customers. This study is meant to help organizations considering Microsoft Cloud technologies understand their current use, the overall customer experience, and the impact of the solutions. Note: In October 2021, Microsoft Cloud for Healthcare became generally available; this solution was not specifically targeted in this research.

Excited by the potential time and money savings, many healthcare organizations want a deeper understanding of what artificial intelligence (AI) and machine learning (ML) technology from public cloud providers could do for them. This research, a follow-up to KLAS’ 2021 report on Amazon Web Services (AWS), examines the experiences of 13 payer and provider organizations using AWS AI/ML offerings. This study is meant to help organizations considering AWS understand what technologies are being used, the overall customer experience, and the impact of these offerings. This report also shares AWS clients’ insights into their selection process and their perceptions of Google Cloud Platform (GCP) and Microsoft Cloud (both of which will be the focus of future reports).
