How to use microservices in healthcare with the HL7 FHIR standard

We're excited to share with you a new article on how to use microservices in healthcare with the HL7 FHIR standard. This approach enables the creation of more flexible and scalable systems that can operate independently of each other. Main components of the architecture Healthcare Services Domain-specific microservices that implement business logic for different healthcare workflows (e.g., patient management, scheduling, clinical documentation). Interact with the FHIR Server through standard FHIR REST APIs and consume events via Subscriptions. FHIR Server Shared data storage that: Provides FHIR APIs for resource storage, retrieval and search Notifies consumers of resource-related events via subscriptions Handles data validation. Terminology Server Manages healthcare vocabularies and code systems (SNOMED CT, LOINC, ICD-10, etc.). Provides terminology validation, lookup, and mapping operations to ensure semantic interoperability across the platform.

We're excited to share with you a new article on how to use microservices in healthcare with the HL7 FHIR standard. This approach enables the creation of more flexible and scalable systems that can operate independently of each other.

Main components of the architecture

Healthcare Services

Domain-specific microservices that implement business logic for different healthcare workflows (e.g., patient management, scheduling, clinical documentation). Interact with the FHIR Server through standard FHIR REST APIs and consume events via Subscriptions.

FHIR Server

Shared data storage that:

Provides FHIR APIs for resource storage, retrieval and search
Notifies consumers of resource-related events via subscriptions
Handles data validation.

Terminology Server

Manages healthcare vocabularies and code systems (SNOMED CT, LOINC, ICD-10, etc.). Provides terminology validation, lookup, and mapping operations to ensure semantic interoperability across the platform.

Infrastructure and Security Services

Cross-cutting concerns including:

Authentication and authorization
API gateway and routing
Audit logging and monitoring
PACS (Picture Archiving and Communication System)
