3 HDR FHIR Server Architecture

Healthcare functional domains (administrative, clinical, and financial) and core services are exposed as RESTful endpoints.

The client application that uses the Healthcare Data Respository FHIR RESTful APIs must properly configure the system in a secure environment to avoid unauthorized access of those APIs. To access protected FHIR APIs, the client application must provide a valid access token.

The FHIR Server can be deployed in a single or multi-node cluster as illustrated below:
