Healthcare organizations, whether operating fully on‑premises, cloud‑native, or hybrid face increasing pressure to expose provider data in standardized, interoperable formats. The HL7 Da Vinci PDex Plan‑Net Implementation Guide establishes a consistent data exchange model, but legacy systems rarely store information in FHIR‑ready schemas. This whitepaper presents a cloud‑agnostic architecture using Azure API Management (APIM), Azure Functions, canonical JSON, and Liquid templates to reliably convert heterogeneous provider data into PDex FHIR Bundles. The guidance herein applies to systems hosted on‑prem, in private cloud, in public cloud platforms, or in multi‑cloud environments, providing a practical roadmap for organizations modernizing their provider directory pipelines.
