Microservices Architecture for HealthTech — UK Specifics

NHS Clinical System Integration Microservices

NHS HealthTech microservices must integrate with multiple clinical systems via different protocols. Integration patterns: FHIR R4 REST (modern NHS systems — GP Connect, PDS), HL7 v2 messaging (legacy NHS lab and order systems — still widespread), DICOM (radiology — PACS integration), and proprietary APIs (System C Medway, Lorenzo, Cerner). Integration microservice pattern: dedicated integration service per external system, normalising to internal canonical data model.

Patient Safety Microservices Architecture

DCB0129 requires a hazard log for each software function that could affect patient safety. Microservices architecture maps naturally to DCB0129 risk decomposition: each microservice is a discrete clinical function with its own hazard assessment. High-risk microservices (medication, dosage calculation, clinical decision support) require Clinical Safety Officer review at the microservice level.

NHS Data Residency in Microservices

NHS DSP Toolkit Standard 7: all personal data must remain in UK or EEA. In microservices: every service's data store must be confirmed in-region (AWS eu-west-2 or Azure UK South). Third-party libraries: check for any telemetry data sent to US servers by default (disable or configure to EU). Service mesh traffic: inter-service calls containing patient data must stay within the UK-region cluster.

Event-Driven NHS Data Sharing

NHS microservices often need to share patient data across care settings. Event-driven pattern: clinical events (admission, discharge, prescription issued, referral made) published to NHS-compliant event bus (AWS EventBridge in eu-west-2), consuming services subscribe and update their own data stores. UK GDPR lawful basis for event-driven sharing: public task (NHS statutory function), documented in Article 30 ROPA.

Frequently Asked Questions

Common questions about healthtech software development.

Can NHS HealthTech use event-driven microservices architecture?

Yes — event-driven microservices work well for NHS applications. Key considerations: UK data residency (use AWS eu-west-2 EventBridge, not global), audit logging (every clinical event published to the bus must be immutably logged for DSP Toolkit audit trail), patient consent tracking (if consent-based processing, consent events must propagate before clinical data events), and FHIR R4 event format (NHS-standard event structure for interoperability with other NHS systems).

How many microservices is too many for an NHS HealthTech application?

There is no absolute limit, but over-decomposition creates operational complexity that can compromise patient safety. ClickMasters guideline: start with service boundaries aligned to NHS clinical domains (patient demographics, clinical records, appointments, prescribing, referrals). Each domain becomes one microservice. Add decomposition only when a domain has genuinely different scaling, team, or compliance requirements.
