Cloud native EPRs are built to exploit cloud architecture from the start, with elastic scaling, faster development, and greater flexibility for change. Cloud hosted systems usually move older software into cloud infrastructure without redesigning the underlying application model. In practice, cloud native designs are better suited to rapid innovation, modular integration, and continuous delivery of new capabilities.
How cloud native EPRs differ from cloud hosted EPRs
Cloud native EPRs are designed around cloud operating models, so elasticity, modular delivery, and rapid integration are part of the product’s core architecture. Cloud hosted EPRs typically keep the legacy application pattern intact and relocate it into cloud infrastructure, which can preserve familiar workflows but limits how far the system can adapt without deeper redesign.
The practical difference is not just deployment location. It is whether the vendor re-engineered the platform for continuous change, API-driven integration, and service decomposition, or mainly shifted an existing product into a new hosting environment.
Why architecture matters more than hosting labels
“Cloud hosted” often describes where the application runs, not how it was built. That matters because a hosted legacy EPR may still carry older release cycles, tighter coupling between modules, and integration patterns that were originally designed for on-premises environments. A cloud native EPR is more likely to support independent scaling, cleaner automation, and faster feature rollout, which changes both operational agility and long-term maintainability.
This distinction also affects how the system absorbs change. If the product was engineered for cloud services, updates can be delivered in smaller increments and integration points are usually easier to extend. If the product was lifted into cloud infrastructure without redesign, the cloud may improve availability and hosting flexibility, but it does not automatically change the software architecture or the pace at which the vendor can innovate.
For teams comparing products, the question is whether the platform’s internal design supports modern delivery and integration requirements, not whether the service sits in a public cloud. That is why two products can both be “in the cloud” but behave very differently in practice. One may behave like a modern modular platform, while the other still behaves like a traditional enterprise system with cloud operations wrapped around it.
What practitioners should look for in vendor claims
The most useful test is to separate infrastructure claims from product-engineering claims. Ask whether the platform supports API-first integration, independent service scaling, frequent releases, and deployment patterns that reduce downtime risk during change. Those capabilities usually indicate a cloud native design rather than a simple hosting migration.
Also check whether the vendor can explain what changed in the application model, not only where the servers run. If the answer is mostly about migration, data centre exit, or managed infrastructure, the product is likely cloud hosted. If the answer includes re-architecting, automation, modular services, and continuous delivery, the product is much closer to cloud native.
A useful vendor conversation is to ask how upgrades, integration changes, and environment separation are handled. Cloud native platforms should be able to describe a repeatable release process and a cleaner path for adding new capabilities. Cloud hosted platforms may still work well, but they often rely more heavily on vendor-controlled release windows and deeper compatibility constraints.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0 and CSA Cloud Controls Matrix set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | GV.OC-01 — Organizational Context | Helps classify the EPR platform as a business capability with cloud operating assumptions. |
| PR.IR-01 — Network Resilience | Cloud native versus hosted changes resilience and scaling expectations for the platform. | |
| PR.DS-10 — Confidentiality and Integrity of Data at Rest | EPR hosting and architecture choices affect how patient data is stored and protected. | |
| Recommendation — Define the vendor and deployment model in the system context before selecting an EPR. Assess whether the deployment model supports the resilience and scaling the clinic needs. Verify that the chosen EPR design preserves required data protection controls in cloud storage. | ||
| ISO/IEC 27001:2022 | A.5.23 — Information security for use of cloud services | Directly applies because the question compares cloud deployment models for a critical system. |
| Recommendation — Assess cloud service responsibilities and controls before accepting a hosted or native EPR model. | ||
| CSA Cloud Controls Matrix | CSA-CCM — Cloud controls matrix | Cloud native and hosted EPRs both require cloud control coverage across architecture and operations. |
| Recommendation — Map the EPR’s deployment model to the relevant cloud control domains before procurement. | ||
Practitioner Guidance
What to verify: Confirm whether the vendor has redesigned the application for cloud operation, or only relocated legacy software into cloud infrastructure. The difference shows up in release frequency, integration flexibility, and how much change the platform can absorb without disruption.
Decision rule: If your priority is rapid capability growth, modular integration, and continuous delivery, treat true cloud native architecture as a material selection criterion. If your priority is mainly infrastructure modernisation with lower transformation effort, a cloud hosted model may still be acceptable, but expect more limits on adaptability.
Practitioner takeaway: The label matters less than the architecture behind it, because cloud native value comes from redesign for change, not from cloud location alone.
