Public Cloud

Public cloud provides on-demand computing resources over the internet. It uses a pay-per-use model with features like self-service, resource pooling, and rapid elasticity. Public cloud service models include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), offering foundational components, development environments, and application access, respectively.

Epic in the Public Cloud 2024: Are AWS & Microsoft Azure Meeting the Expectations of Early Adopters?
07 November 24
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 href="/report/approaches-to-moving-epic-in-the-cloud-2023-which-public-cloud-providers-are-early-movers-considering/3124" target="_blank"><u style="color:#4c8bc9;">a report</u></a> 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.<br><br> <p style="font-size:.85em; color:#858d96;">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.</p>

Report Abstract

Key Findings:

  1. Public Cloud Scalability: While Market Is Still Early, Large Organizations in Full Production Environments Report Success with Both AWS & Microsoft Azure
  2. Technology, Speed & Support Drive Strong Satisfaction for AWS Customers; Microsoft Azure Customers Appreciate Platform, though Inconsistent Support & Relationships Affect Overall Satisfaction
  3. AWS Customers Report Improved Performance & Microsoft Azure Customers See Consistent Results; Cost Savings Not Yet Realized for Either Customer Base
  4. Healthcare Organizations Cite Integration & Internal Expertise as Biggest Challenges
  5. Use of Third-Party Firms for Cloud Planning/Assessment & Migration Is High

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.

Public Cloud Providers 2022
08 December 22    |   Mike Smith and Sam Eaquinto
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.

Microsoft Cloud Technologies in Healthcare 2022
25 August 22    |   Mike Smith and Sam Eaquinto
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.

AWS in Healthcare 2022
07 June 22    |   Emily Paxman and Mike Smith
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). To learn how KLAS defines AI and ML, see Healthcare AI CHIME Edition 2019: Actualizing the Potential of Artificial Intelligence .



Reducing Filters

Unlike sizing filters, reducing filters DO NOT recalculate scores based on the evaluations that meet these requirements. They narrow the list of solutions to show the vendors and solutions that can meet a specific need.

This data is based on interviews with a sample of the firms' recent clients. As a result, it is not necessarily comprehensive of all work a firm may do in this segment.

We require a minimum of 2 confirmations of a service performed in the last 3 years for a solution to qualify.
