As of 2025, the ambulatory EHR market has seen a decisive shift toward Cloud-Native Architectures, with the cloud-based segment now accounting for over 84% of new installations. Unlike legacy on-premise systems, cloud-based EHRs utilize a "SaaS" (Software as a Service) model, allowing small-to-medium practices to bypass the high capital expenditure of in-house servers and specialized IT staff.

Technically, these systems leverage Multi-tenant Microservices, enabling real-time updates and seamless scaling as a practice grows. According to the Ambulatory EHR Market 2025 technology review, cloud integration is the primary driver for "Data Liquidity," ensuring that patient records are accessible across multiple satellite clinics or urgent care centers. This architecture also facilitates automatic HIPAA-compliant backups and end-to-end encryption, significantly reducing the cybersecurity burden on independent outpatient providers.
