eHealth Architecture
Throughout the documentation, the term eHealth Infrastructure refers to the services provided on the platform.
Starting from the bottom of the figure, the system contains:
Technical Infrastructure - This is the computing, networking and storage part.
Platform - this is Kubernetes, internal databases and more
Platform cross-cutting concerns:
Security
Logging
Deployment Model
Messaging
eHealth Services - The eHealth services are exposed to third parties for developing Telemedicine Solutions.
eHealth Applications - End-user application provided as part of the eHealth Infrastructure.
Telemedicine Solutions - End-user application provided by a third party.
Backend-for-frontend (BFF) - Design Pattern for rather than having a general-purpose API backend, a BFF expose a specialized backend per user experiences.
eHealth Application BFF - backends for applications provided with the eHealth Infrastructure, see eHealth Applications.
Solution Application BFF - a vendor providing a Telemedicine solution may choose to add its backend that consumes the eHealth Infrastructure services whilst providing an API towards the application client. The vendor may choose to let the application consume eHealth services directly or use a hybrid between BFF and direct invocation.
Application Client/Service - It is expected that applications/services (Danish: fagsystemer) used by healthcare providers, social providers or social care providers will consume eHealth Infrastructure services directly, but they, too, may choose to use a BFF.
Domains
Overall, the services of the eHealth Infrastructure are divided into three domains elaborated in the following.
Administrative Domain
The Administrative Domain contains generic services and resources, that is, services and resources that are not specific to patients/citizens.
How to interact with these services is elaborated in https://ehealth-dk.atlassian.net/wiki/spaces/EDTW/pages/512950429.
Clinical Domain
The Clinical Domain contains services that provide patient/citizen-related resources. They make use of the services and resources in the Administrative Domain.
How to interact with these services is elaborated in https://ehealth-dk.atlassian.net/wiki/spaces/EDTW/pages/539459601.
Service, Support and Logistics (SSL) Domain
The Service, Support and Logistics (SSL) Domain contains services for managing catalogues of services and devices and ordering these services and devices.
How to interact with these services is elaborated in Interacting with Services in the SSL Domain
System Context of eHealth Infrastructure
As depicted below, the eHealth Infrastructure is integrated with several external systems, most of which are provided by the Danish National Health Data Agency (Danish: Sundhedsdatastyrelsen) through the National Service Platform (NSP).
The following services are sources of information consumed by the eHealth Infrastructure:
NSP Stamdata CPR Enkeltopslags Service (SCES) for citizen ID (CPR) lookup - Documentation (In Danish): https://www.nspop.dk/pages/releaseview.action?pageId=1573053,

Sundhedsvæsenets Organisationsregister (SOR) the National Health Organisation Registry - Documentation (In Danish):
KOMBIT Fælleskommunal Organisation (FK Organization) formerly known as Støttesystem Organisation (STS-ORG) which is Municipal Organization Registry - Documentation (In Danish):
Danmarks adresseregister (DAR) with Web API (DAWA) which is the Danish Address Registry - Documentation: https://eng.sdfe.dk/products-and-services/the-danish-address-register
The following services receive information from the eHealth Infrastructure:
